The High Elf rogue who first received the Anarchist's Cookbook in the fifteenth season — its original disguised owner.
Porthus is named in the Cookbook's own history as the crawler for whom the 24th-edition book was first generated: a High Elf Rogue who received it on the ninth floor during the fifteenth season, disguised as a blank sketchbook. Nothing else about him is knowable to Carl at this point — only that the secret manual of dungeon chaos began, generations of crawlers ago, in Porthus's hands before passing down season to season to its current keeper.
Not described; known only as a High Elf rogue of a past season.
The original recipient of the Anarchist's Cookbook, a name from its lineage.
