Chronicles of Khaldun: Bread and Circuses
A primordial, fish-like entity from the Far Realm, this particular aboleth lurks far below the streets of Scandshar, in a series of underground rivers. Its purpose and desires are unknown, although it sent some minions to recapture Croitus, as he evidently escaped the creature’s realm more-or-less unscathed.
Croitus, for his part, is exceedingly interested in knowing what such a vile creature is doing beneath Scandshar.
