"That is a sufficient name as any other," He replies, before adding, "As for leaving... I'm not sure the dungeon will let me... It changes, exits disappear, and wall re-arrange themselves. Besides, going with you would imply going to a human population center... In my experience the more humans are around, the less welcome I am in a given area. As for my kin... I can't say I know anything about that. I have not met many myself." Not an irrational concern. As it is, if you matched on out followed by an owlbear, the guards would like shit themselves, possible even attacking Cikuma. With that said, and even if the dungeon wishes to keep him here... You are a summoner, it is quite possible for you to summon him past all the humans, similar to a ritual spell, except it lacks the return feature, though you would need something to serve as a tether, like a feather of his. Speaking of ritual summoning though, you doubt you are powerful enough of a summoner to summon him with a simple spell, so he would definitely be a ritual summon, even with a pact.
As you continue on with your suggestion for a pact, you are sense a deep apprehension, as he replies, "Perhaps, but I do not believe rushing into a pact is a wise move. I wish to consider it and it's terms in more detail."

Ah, I knew Kuma, and figure Ci meant owl, but wasn't sure from where... Also, I constantly wrote his name as Chikuma and had to correct it.
