Concept: “Ancient god-vessels of cursed skin and soot-black wood, as rare and as valuable as they are blasphemous.”
Content: 4 sets of 8 powers granted by dead folk gods
Writing: Simple and straightforward mechanically; minimalist but seething with character and tone
Art/design: Black-and-white art on black ground beside white text; the graphic design is as maliciously expressive as the visuals
Usability: Covers are blank to ensure random selection; red page headings facilitate quick reference

Note: Original run was misprinted the first and last inside pages on the covers
