Curse of the Crimson Throne
Imps are a common sight in the skies above Korvosa, often fighting with their natural enemies, the local house drakes population. These tiny devils are summoned by Acadamae students as part of their graduation requirements, but some are unable to fully bind them or otherwise lose control of them. The imps escape into the city where they form into small packs, looking for mischief. They are a particular nuisance in the roof-level Shingles, and often try to form alliances with gangs or other ne'er-do-wells.
