An expedition assembled at great cost is a bust, the scribe's map a forgery, the treasure a mere bard's tale. The only hope to escape these shattered lands and the pursuit of a host of undead nightmares is to answer the desperate dream call of an archmage trapped in a sinking tower. If the tower can be freed from the elementals dragging it beneath the earth, it can transport all within to safety. With the howls of pursuit closing in, the battlement of the tower comes into view at the bottom of a ravine ... the rest of the tower already sunk deep within the earth. The time to escape is fleeting, the only way forward is down into darkness.
