The adventurers learn of a rare opportunity, once every decade the tides recede to reveal a mysterious undersea tower. Ages ago this was the lair of Sezrekean the Elder, the most wicked, foul wizard to trouble the known lands but now its the resting place of a cursed artifact that brings doom to those who possess it – the Black Pearl. Tonight as the moon shines down and the tides pull back, a brave party of adventurers have 8 short hrs to solve eldritch puzzles, dodge ancient traps, and overcome the evil of the tower to win the prize of the Black Pearl before the ocean reclaims its own. Unfortunately a local band of pirates have the same idea. Can the brave adventurers overcome all to win the prize?
