You seem to get in with a few old dogmen in your area, start asking for who they respected in the pits. Then if you're able, scribe a hand written letter describing your desire and intent.
Then pray.
I dont think youve described anything out of the realm of possibilities for a true game pit. They aren't bulked up bad boys or dumb brutes. Well actually, what do i know, im still in the process of finding the man to write a letter to.
