Tihtarus prefers a form that inspires the idea of brute force. His known form on Dawn is a mountain that he shaped to move when he commands it. It is unknown what mountain he uses for this task as multiple large stone sculptures have been found on mountains throughout Bedias.
Tihtarus is one of the least worshipped Dez'ran as the Dwarves aren't very religious and more technologically focused than other races. He is credited for creating all mountains and valleys on Dawn and for making mines safer if prayed to. His use of brute force matches how the Dwarves have little to no magical ability.
