He became interested in acquiring a legendary and valuable Horn of Quintus hidden in the Bonehoard. He found a rough map of the catacombs, and wrote down some notes on the location. Once he had all his information, he got together a party of thieves, namely Dranko, Marcus, Sutter and Cather, left his notes with Cutty, and then headed in. A series of accidents left Felix without his crew, but he continued the hunt alone. He did manage to come close to locating the horn, but he eventually died, presumably killed by Zombies, in the Halls of Echoing Repose.
