A mysterious crystal citadel gleams under twin moons in this best puzzling mystery short legend

The Citadel

This tale weaves together ancient secrets and forgotten magic. One of the best puzzling mystery short legends of our time, it follows a scout’s journey to uncover the truth behind a crystal fortress and the strange disappearances plaguing the borderlands. What begins as a simple mission becomes a race against dark forces bent on awakening what should remain dormant.


Chapter 1: The Assignment

Elian folded the map carefully. Twice lengthwise. Once across. The thin parchment crackled between her fingers. “Are you certain of this?” she asked. Commander Torvald nodded. His gray beard caught the lantern light. “The Council needs answers. Five villages empty in half a moon’s turn. No signs of battle. No bodies.” “And all near the old border?” “Yes. Near the Crystal Citadel.” Elian frowned. Every child knew the stories. A fortress of glass and light built by the ancients. A place of power. A place to avoid. “The Citadel is just a legend,” she said. Torvald’s eyes hardened. “Is it? Then explain this.” He placed a clear crystal shard on the table. It pulsed with inner light. Blue. Then purple. Then blue again. “Found clutched in a child’s hand. The only trace left in the last village.” Elian picked up the crystal. It felt warm. Almost alive. “You leave at dawn,” Torvald said. “Find the Citadel. Learn what happened to those people. And Elian…” His voice dropped. “Trust no one. The Council has enemies even they don’t know about.”


Chapter 2: The Journey

Three days of hard riding brought Elian to the edge of the Shadow Woods. The border lands. No one came here anymore. Not since the Great War centuries ago. Her horse, Ash, snorted nervously. Animals always sensed danger first. “Easy,” she whispered, stroking his neck. “We’re just passing through.” The woods grew thicker. Darker. The trees seemed to lean inward, watching. By midday, Elian found the first village. Wellspring. Population sixty-three. Now zero. Homes stood empty. Meals half-eaten on tables. Doors left open. As if everyone had simply walked away. No blood. No signs of struggle. Just absence. In the village square, Elian noticed strange markings carved into the well. Fresh marks. Symbols she’d never seen before. She copied them into her journal and continued on. The second village was the same. And the third. By the time she reached the fourth, Elian could feel it—a pull, subtle but insistent, drawing her northeast. Toward the mountains. Toward where the Crystal Citadel would be, if it existed. That night, camping in the remains of the fourth village, she dreamed of voices. Whispering. Calling. Promising answers. She woke clutching the crystal shard Torvald had given her. It glowed brightly now, pulsing in time with her heartbeat.


Chapter 3: The Discovery

The mountains rose like teeth against the morning sky. Jagged. Unwelcoming. According to her map, there should be nothing here. Just wilderness. Yet as Elian crested the ridge, she saw it. The Crystal Citadel. It erupted from the mountainside. Towers of gleaming crystal caught the sunlight. Walls that seemed both solid and fluid. A massive structure that should not exist. “Impossible,” she whispered. The crystal shard in her pocket burned hot. Pulling her forward. Leaving Ash tethered safely away, Elian approached on foot. The great doors stood open. Welcoming. Inviting. Too inviting. Inside, the air felt thick. Heavy with magic. The walls pulsed with the same rhythm as her crystal shard. Footprints marked the dusty floor. Dozens of them. All heading deeper inside. Elian drew her sword and followed. The entrance hall opened into a vast chamber. Crystal columns stretched hundreds of feet to a domed ceiling. In the center stood a raised platform with a pedestal. And on that pedestal—a book. Elian approached slowly. The book lay open. Its pages filled with the same strange symbols she’d found in the villages. As she reached for it, a voice spoke. “I wouldn’t touch that if I were you.” Elian spun, sword ready. A man stepped from behind a column. Tall. Dark-robed. His eyes unnaturally bright. “Who are you?” she demanded. “My name is Varen. I’m the keeper of this place.” He gestured around. “Or I was, until recently.” “The keeper? But this place is—” “A legend? Yes, that’s what we wanted everyone to believe.” He sighed. “Much safer that way.”


Chapter 4: The Keeper

“We?” Elian kept her sword pointed at Varen’s chest. “The Order of the Crystal,” he explained. “We’ve guarded this place for centuries. Keeping its power contained.” Varen looked tired. Wounded, perhaps. He leaned on a staff topped with a crystal identical to the one in Elian’s pocket. “What happened to the villagers?” she asked. “They were taken. Called. The barriers between worlds are thinning, and something is pulling them through.” Elian lowered her sword slightly. “Something like what?” “Have you heard of the Dragon Gods?” Everyone had. Ancient beings of immense power who’d ruled before humans. Defeated in the Great War and banished beyond the Veil. “They’re trying to return,” Varen said. “And they need vessels. Human vessels.” “The villagers?” He nodded. “This Citadel was built as a prison and a gate. The crystals maintain the barrier. But someone has been sabotaging our work.” “Who?” “The Cult of Scales. Humans who worship the Dragon Gods. They believe transformation—becoming vessels—will grant them immortality.” Elian thought of the empty villages. The strange pull she’d felt. “How do I know you’re telling the truth?” Varen smiled sadly. “You don’t. But the crystal you carry—it’s part of the keystone. Only those with pure intentions can touch it without burning.” Elian pulled out the crystal. It glowed softly. “The other keepers are dead or fled,” Varen said. “I’m the last. And I need your help.”


Chapter 5: The Puzzle

Varen led Elian deeper into the Citadel. Each chamber more magnificent than the last. All built of the same pulsing crystal. “The heart of the Citadel lies below,” he explained. “The keystone chamber. That’s where the barrier is weakest now.” They descended spiral stairs that seemed to float in mid-air. The magic grew thicker. Harder to breathe. “Why me?” Elian asked. “Why am I here?” “The crystals choose those who can help. They called to you through your dreams, just as the Dragon Gods call to their worshippers.” The stairway ended at a sealed door. Complex patterns covered its surface. “The entrance to the keystone chamber,” Varen said. “It requires a sequence to open.” He pointed to seven crystal nodes embedded in the door. Each a different color. “Touch them in the wrong order, and the defenses activate.” “What happens then?” “Nothing pleasant.” Elian studied the door. The symbols matched those from her journal—the markings from the villages. “The villages,” she realized. “They form a pattern on the map. Each was targeted in sequence.” She checked her notes. First Wellspring, then Oakvale, Rivermeet, Highcross, and finally Eastwatch. “Five villages. Five colors.” Elian touched the blue node first, then green, blue again, yellow, and finally red. Nothing happened. “Five villages, but seven nodes,” Varen said. “We’re missing something.” Elian thought. “Wait. The crystal I carry—it pulses in a pattern. Blue, purple, blue.” She touched the purple node, then the blue again. The door rumbled open. “Well done,” Varen said, smiling. “Though I expected nothing less from Torvald’s best scout.” Elian froze. “I never told you who sent me.”


Chapter 6: The Betrayal

Varen’s smile turned cold. “No, you didn’t.” His form shifted. Rippled like water. The tired old keeper vanished, replaced by a younger man with sharp features and reptilian eyes. “The keeper’s appearance served its purpose,” he said in a new voice. “Gained your trust, didn’t it?” Elian drew her sword. “Who are you really?” “Dravos. High Priest of the Cult of Scales.” He bowed mockingly. “And thanks to you, we now have access to the keystone chamber.” Guards emerged from hidden alcoves. Six cultists in scale-patterned armor. Each with the same reptilian eyes. “The transformation has already begun for my followers,” Dravos explained. “Soon they’ll be vessels for the Dragon Gods’ return.” “The real Varen?” Elian asked. “Dead. Along with the other keepers. We’ve spent years infiltrating the Order, learning its secrets.” Dravos gestured toward the open door. “Now, shall we?” One cultist grabbed Elian’s arm. She reacted instantly—sword flashing. The cultist fell back, clutching a wounded shoulder. But there were too many. Two more seized her. Another took her sword. “Bring her,” Dravos ordered. “She opened the door. Her blood will open the final seal.” They dragged Elian into the keystone chamber. The room was perfectly circular. In its center floated a massive crystal, pulsing with energy. Cracks spread across its surface. “The keystone,” Dravos said reverently. “The barrier between worlds.” Around the edges of the chamber stood stone pedestals. Five held crystal shards—identical to the one Elian carried. One pedestal remained empty. “We’ve spent months collecting the shards,” Dravos explained. “Pulling them from the villages, weakening the barrier. Yours is the last piece.” He held out his hand. “The crystal, scout. Now.”


Chapter 7: The Choice

Elian assessed her options. Six cultists. All armed. No obvious escape. But something about the chamber felt…wrong. The floor patterns didn’t match the door’s symbols. An inconsistency. “If you want the crystal,” she said, “you’ll have to take it.” Dravos sighed. “Always the hard way with your kind.” He nodded to a cultist who stepped forward, dagger drawn. Elian tensed, ready to fight. But before the cultist reached her, a voice echoed through the chamber. “Enough!” Everyone turned. In the doorway stood an old man—robed, white-bearded, leaning on a crystal staff. “Varen?” Dravos looked shocked. “How—” “Did you think I wouldn’t prepare for betrayal?” The real Varen stepped into the chamber. “Did you think I wouldn’t recognize one of my own initiates trying to steal my identity?” Power radiated from the old keeper. The air crackled around him. Dravos recovered quickly. “Kill him!” Two cultists charged Varen. With a gesture, the keeper froze them in place. “The Crystal Citadel responds to its true keeper,” Varen said. “Not impostors.” While Dravos was distracted, Elian made her move. She drove her elbow into one guard’s stomach, twisted free, and grabbed her sword from another. Chaos erupted. Cultists attacking. Varen defending. Elian fighting her way toward the door. But Dravos ignored the battle. He rushed to the keystone, pressing his hands against the fractured crystal. “Brothers beyond the Veil,” he chanted. “The way opens!” The keystone’s cracks widened. Dark energy spilled forth. The chamber shook. Varen shouted to Elian over the noise. “The crystal you carry! Place it on the empty pedestal!” She hesitated. “How do I know you’re really Varen?” “You don’t,” he admitted. “But consider the alternative.” The keystone pulsed violently. Through its cracks, Elian glimpsed another world. A realm of shadow and scale. Massive forms moving. Waiting. She made her decision.


Chapter 8: The Sacrifice

Elian fought her way to the empty pedestal. Two cultists moved to intercept her. Varen’s magic caught one. Elian’s sword took care of the other. She reached the pedestal and pulled out her crystal shard. It burned white-hot now, almost too painful to hold. Across the chamber, Dravos saw what she intended. “No!” he screamed. “Stop her!” Elian placed the crystal on the pedestal. Light exploded from all six shards. Beams connecting, forming a cage around the keystone. “It’s working!” Varen called. “The barrier strengthens!” But Dravos wouldn’t be denied. He plunged his dagger into the keystone’s surface. Cracks spread faster than the light could heal them. “The sixth crystal isn’t enough,” Varen said grimly. “We need a seventh.” “There is no seventh shard,” Elian shouted over the growing cacophony. “There is.” Varen pointed to his staff. “My staff crystal. The master key. But only a true keeper can remove it.” He looked at Elian meaningfully. “Or someone chosen by the crystals themselves.” Understanding dawned. The crystal had called to her. Chosen her. “What do I do?” “Take my staff. Place the crystal in the center of the keystone. It will seal the barrier—permanently.” “And you?” Varen smiled sadly. “A keeper’s life is bound to the Citadel. This was always my fate.” The chamber shook violently. The barrier between worlds thinned further. Through the cracks, enormous clawed hands reached through. Elian lunged for Varen’s staff. The keeper surrendered it willingly. As her hands wrapped around the crystal top, energy surged through her. Knowledge. Power. The history of the Citadel and its purpose flooded her mind. She understood now. Dravos saw her intention. “Kill her!” he commanded his remaining followers. Varen stepped between them. “Go, Elian! Finish this!” The old keeper raised his hands. Crystal spikes erupted from the floor, creating a barrier. Elian ran to the keystone. Dragon God essence poured through the cracks. The air turned sulfurous. Burning. With all her strength, she thrust the staff crystal into the keystone’s center. Light erupted. Blindingly bright. A shockwave threw everyone back. In that moment, Elian felt the villagers. Hundreds of souls suspended between worlds. Pulled toward dragon forms waiting to inhabit them. With the power of the keeper temporarily flowing through her, she made a choice. She pulled them back.


Chapter 9: The Return

When Elian’s vision cleared, the keystone glowed steadily. Whole again. The cracks sealed. Dravos and his cultists lay unconscious on the chamber floor. But Varen was gone. In his place, a crystal statue—a perfect likeness of the keeper, one hand raised in final defense. “Thank you,” Elian whispered to the statue. A groan from behind her. One of the cultists stirring. But something was different. The reptilian eyes were gone. Replaced by confusion. Humanity returned. As the cultists woke, Elian realized what had happened. Without the Dragon Gods’ influence, the transformation had reversed. And around the chamber, forms materialized. People. Confused. Disoriented. The missing villagers. A small girl approached Elian. “How did we get here?” “You were lost,” Elian said gently. “But now you’re found.” In the days that followed, Elian led the villagers home. Each city reoccupied. Lives resumed. But not all returned. Some had gone too far in the transformation. They remained in the chamber, crystallized like Varen. Dravos was among them. Perhaps that was justice. Before leaving the Citadel, Elian visited the keystone chamber one last time. The crystal now glowed with steady, healthy light. On impulse, she placed her hand on the keystone’s surface. Knowledge flowed into her mind. The keeper’s knowledge. The Citadel needed a guardian. Without one, the barrier would eventually weaken again. Elian understood her new purpose. The crystal had chosen her for a reason. She thought of Torvald, waiting for her report. Of the Council, expecting answers. Some secrets weren’t meant to be shared. As Elian left the Citadel, she removed a small crystal from her pocket—a splinter broken from the staff. Insurance against future threats. The great doors closed behind her. Not forever. She would return. After all, a keeper’s work was never done.


Epilogue

Commander Torvald read Elian’s report with growing concern. “The villages have been resettled,” she concluded. “Their disappearance remains unexplained, but the threat appears neutralized.” “And the Crystal Citadel?” he asked. “A legend, nothing more,” Elian replied smoothly. “I found no evidence of such a place.” Torvald studied her carefully. “You’ve changed, scout.” Elian smiled. “Haven’t we all?” That night, under twin moons, Elian slipped away from the outpost. A long journey awaited her. A new role. A sacred duty. In her pocket, the crystal splinter pulsed. Blue. Purple. Blue. Calling her home.
