An Adventure for Children of the Apocalypse
From the introduction:
The Tower of Fogaren has stood for centuries in the town of Orange. Once, the Fogarens ruled the community through a series of puppet Lords of Orange, but with the advance of the Rahelian Empire, they were forced to yield to Count Thomas Muñoz. The family has never forgotten their past glories, nor have the Counts Muñoz forgotten the various schemes that Fogarens have enacted to regain power. Most recently, Egbert Fogaren attempted blackmail against the Count, who retaliated by sending a hired Rogue’s Congregation assassin. The assassin reached Egbert but also triggered the tower’s magical defenses, and both now lie dead on the top story, surrounded by powerful and valuable magical artifacts.
