Gruton

An oversized dragon turtle that roams the seas searching for prey to devour. His main goal in life is thwart his brother Krillon and establish dominance of the waters between the mainland and Kurnst.
It is rumored that he originally created the first magics that we would consider the school of abjuration. His hardened shell and tough exterior were the inspiration for defensive magics which he developed to defend against his brothers onslaughts.
