AC:DM Bestiary Description
Mattekars are a strange, fur-bearing variety of reed shark found in the snowfields and mountains of Dereth Island. They are also known, among common folk, as “snow sharks.” They are huge — seven feet or taller at the shoulder — and are found as lone rogues and small family units: the latter will defend one another to the death. They attack with claws, horns and teeth, and are particularly resistant to damage due to cold.
