Crabs

Crabs are an old faction in Caves of Qud that initially dislike the player character. They all have skills in the Cudgel tree, since their pincers are considered cudgels.

Culture
Crabs are one of the few factions that have two kinds of legendary generation, and both of them pull from different corpuses. The first kind only applies to legendary, who have names that focus on hard consonants like k, t, x, and c. This is similar to how crabs speak by "raucous croaking".

The second name generation has a more varied sound palette and are used for dynamically generated legendary crabs. There is no explanation to why these differences exist or what it says about crab society.
