Motif · Book 4, The Gate of the Feral Gods
The marketplace
A personal-space upgrade bought early on the fifth floor: an eBay in the wall, on Donut's account for her Charisma discount, that values Donut's hats at a gold piece each and the Cookbook — per Batbilge's last note — at fifty million. It opens properly on the sixth floor, when the factions and tourists buy every magical item crawlers will sell, to use on each other and, on the ninth, on the crawlers.

Progression
Bought early on Donut's account; hats worth a gold piece; the Cookbook not to be carried near it (ch. 3); Meadow Lark's too, with private sales at half value or more (ch. 10); a magic sheet that could put scrolls on it (ch. 13). The ninth floor's version is real shops, and Carl drowns them (ch. 34).
