When Karl Whitepaw underwent his first Obligation, he sired a son to Acacia who promised that Karl could have a role in her child's raising. Tankar enjoyed a very close relationship with his father, and did many of the things with him that Karl had done with his own children, especially the family's love of baseball. Tankar turned out to be a talented musician and was often the centre of attention at festivals where he would play the foxtaur fiddle either solo or with the band. He also broke his mother's family problem of producing only daughters by siring an average of 40% male kits with his denmates and through Obligation.
