Myx

A Servine — a rare creature resembling a cross between a leopard and a large dog, with eyes that change colour based on emotion and trust. Myx was bred in fighting pits, abused and starved, until he shared a bone with a starving boy named Rook in an alley. Despite appearing fearsome, Servines are deeply loyal and affectionate. Myx communicates through presence and thought-shapes rather than words. His harrowing run through the Fray cracked open Sera's tower and made Rook's retrieval of the third Shard of the Pattern possible.
