A dead sister named twice in one sentence of a manual, as the reason a crawler wanted to kill a god.
Barkith exists in the Cookbook only inside Crawler Forkith's 20th-edition note on deities. Forkith writes that the gods still feel pain, still bleed, and that their drivers suffer — and that in honour of his sister he prays he makes it to the twelfth floor just so he may slay one, look the god in the eyes and say: this is for Barkith. This is for my sister.
Nothing else about her is recorded.
The dead sister behind the Cookbook's one vow of vengeance against a god.
