In-dungeon guild for the Poisoner class, where Tipid worked as an instructor after his crawl.
The Poisoners Guild is the guildhall organization serving the Poisoner class. After taking his deal at the beginning of the twelfth floor, Tipid fulfilled his contract working inside the dungeon as a Game Guide and Guildhall Instructor for the guild, plus occasional shifts as a city guard — with perfect marks across all of it, as Damien notes when processing his release.
His years teaching there also fed the Fourth Edition of the Dungeon Anarchist's Cookbook, which he went on to write.
Tipid's post-crawl employer and the institutional home of the Poisoner class.
