It could be someone who is firmly imbedded in slave culture, could be someone having doubts about slavery, but not actively freeing them yet. You don't even have to become his bondmate, though a male bondmate is eventually what I'm looking for. Kaitanu is a horse Kelvar who has never bonded, has been a slave all his life, and is pretty darn traumatized. His character sheet is here http://www.mizahar.com/forums/post387088.html#p387088 At the moment, I have him just being sold off in Kenash by his last master, but I can change that if it's too much for your character to move from where you are.
Let me know if you want to buy him, or even eventually be his bondmate. If you just want to buy him, that's fine. It'll give him, and me, experience. If you want to eventually be his bondmate, be warned. It will take time to break through the damage done by years of slavery, so please be patient. (And also bear with me if I'm not sure what I'm doing. I'm new to the site, though not exactly to rping).
Excited to start playing!
