Naiad

Summon your Naiad minion. An entity born of the ice-wielding familiar Nereid. That's the purple one.

This peculiar entity appears to have manifested from Nereid, the ice-wielding familiar that served among the collective of three that controlled the weather on the Occult Crescent. Though its sense of morality has faded over the course of long years, in this diminutive state, it should largely be harmless.
