Crasher wasn't looking to lead a pack, and if he could, he'd live on his own. But, in order to survive you need a family to watch your back. Crasher (with Tala's help) met Elusion, another wolf trying to survive. The two became close friends and now care for two pups together.
Crasher since then plans on spreading his bloodline. He doesn't think his pups Gard and Grounder will become anything more than hunters, but refuses to let them leave unless they chose so.
