From the introduction:
This is the fourth follow-up adventure to the module Leilon: City of Adventure, which provides an overview to the ruined town destroyed by the Spellplague over 100 years ago. In this adventure the PCs explore the ruined tower of Thalivar the Mage. The tower was the focal point of destruction when the Spellplague struck and the horrors of the tower emerged to wreak havoc upon the town. Now, all that remains of the tower are a few of the top floors that magically float above the ruins below. This module details the tower itself and not the mines below the tower. This is a 15 page adventure with a mostly straightforward layout consisting of several combat encounters mixed with investigation and NPC interaction.
A 1-2 night adventure for 8th-9th level characters
