Shaerael
The Citadel of Shaerael was a well-known landmark¸ administered by a respected lord. Unfortunately¸ his steward - a wicked man and a secret practitioner of the black arts - secretly betrayed Shaerael to an enemy power. The plan went into motion¸ resulting in the lord's death. But the enemy leader¸ having ambitions of his own¸ turned on the steward¸ who in turn tried to defend himself with dark magic.
Something went wrong. All within were slain¸ and Shaerael itself disappeared. But every so often¸ when the stars align right on the night of the full moon¸ the citadel reappears¸ looking as though not a day had passed. Rumors abound that a great treasure is within¸ but a terrible curse awaits any who dare its walls...
