Background: Tarken as Mandalorians go is a grizzled old veteran of Life and deserves respect. His hair is grey do to age and the stress of being the Clan Patriarch, A position that only makes his life harder since a few other clans dislike Clan Kain. He has survived more than one failed attempt on his life, partly thanks to his experience and the other part to his family. Tarken is devoted to his wife Jari as well as his three children Kraal, Jemeraa, and Tolis. He does see his ‘Nephew’ Tarik a bit like a son he wished he had, but knows that it is not the way the galaxy decided things. He like his children and ancestors harbors a distrust of the empire, but it is manly aimed against those who sided with the Sith. He is usually found in the family’s fortress on Mandalore.
