He answers Coolie's warning with a vow: the gods bleed, and he intends to look one in the eye and say his sister's name.
Forkith's 20th-edition note in The Dungeon Anarchist's Cookbook follows directly under Crawler Coolie's advice to stay away from deities, and rejects the spirit of it. They may be invulnerable, he writes, but they still feel pain, they still bleed, and the drivers of these bodies suffer. In honour of his sister he prays he makes it to the twelfth floor just so he may slay one — and that he will look in the god's eyes and say: this is for Barkith.
This is for my sister. He knows it is only a dream.
