Peter Kitsuné doesn't talk much about his past. Some people might remember him arriving in the Old World in mysterious circumstances, with no idea how he got there or where he was. He actually isn't native to the Old World, but rather comes from another world named Furth. On Furth he received an ancient curse, which would eventually kill him, or worse.
Soon after arriving in the Old World, Peter rescued an injured she-wolf cub that he found. He named the wolf Akira, a name that means "Morning Sun". Some might find it strange that a wolf and a kitsune would become friends, but friends they became.
In time, Peter signed up for the adventuring guild and went through the Portal into the New World. The first thing he discovered was the magic - thick enough he could almost taste it. The second thing he noticed was that his curse was gone. Or - not gone. But suppressed. Something about the New World meant the curses of Furth didn't function here, or something.
Now, having gained a primal connection to Akira's mind, the two are willing to go into battle together with some strangers, and fight foes together that cannot be fought alone. And maybe even make some new friends?
Either way, it looks like they're going to have a good time here in the New World, Beyond the Portal.
