Thatug is the leader of House Jagrer.  Like most members of his house, Thatug was raised, starting at a very young age, in combat and the art of war.  Being both an impressive warrior and tactician, Thatug quickly rose in the ranks of the Wilder Clan's military, eventually becoming the commanding general, serving under Warlord Zarmn.

 

After Voonder killed Zarmn and became the clan's new leader, Thatug was forced to retire, as were most of Zarmn's loyal staff.  Voonder replaced Thatug with Hanz, and there has been tensions between the two of them ever since.
