The dark age of Athas
an Ugly, powerful Slaver who owns the Leviathan and rules it with an iron fist.
seems to perhaps have a soft spot for brutal pit fighting slaves, which he often tries to recruit to his crew.
those who displease him are thrown to the Constrictors, a horrible creature(s) which resembles a series of long giant tentacles, each ending in a mouthed claw.
Bloth keeps the constrictors in one of the expansive holds of the Leviathan, and has made it accessible from every level of the vehicle, just incase he need someone out of his sight, permanently.
