Concept: “CY is a great beast and these are its bowels, the living guts of the city. Awash in filth and the prowling grounds of criminals, scvm beneath notice, maintenance workers, bounty hunters and strange monstrosities bred in the noisome darkness beneath this city. Features a d66 table of encounters in the sewers of CY and a d20 table of tunnel graffiti.” 

Content: A set of tables to flesh out the grimy, dangerous CY undercity.

Writing: Vivid descriptions of encounter seeds (not only who/what players might find but what’s going on when they find something) and graffiti messages and styles to be found on sewer walls.

Art/Design: Black text on yellow in a single column of text. A glitch-art illustration of a sewer tunnel frames the supplement title on the first page.

Usability: Tables are numbered, with bolded labels for NPCs and their special attacks to emphasize details a GM might be scanning the page to locate.
