Cania

Cania is the frozen Eighth Circle of Hell. It is ruled by the ambitious Mephistopheles, Lord of Ice, and anchored by his great glacier Nargus at its center. While devils (and the Outer Planes more broadly) dither endlessly over the disposition of souls, Cania is traditionally the destination of deceivers, corrupt purveyors of power, and those who use magic for evil ends.

Adonides was from Cania.
