Publisher's blurb:
A nearby door flies open; Russ Tanner holds up a key. “Take it!” he croaks. “You can’t let them get ‘the Key!’ There’s too many; take it and run!” As Russ Tanner slumps over; brutal blows begin to rain against the sturdy wooden door. Enemies are trying to break in. A crack opens revealing a one giant, angry eye: a Cyclops. Russ Tanner drops the key as he whispers his last words, “it opens every door!” Tanner dies with a groan.
Mysteriously linked to seemingly ordinary objects, the Lost Tower holds a power which empires will war to obtain. The adventurers have the most important object fall into their hands: the key to the Lost Tower. And now everyone wants to kill them.
An 8-12 hour (or longer) Fifth Edition Dungeons & Dragons adventure suggested for all alignments.
