Shayuri--your post is long so I won't quote it all because then everyone will have to look at the big quote
Some interesting ideas there. Let me take a look at each, one at a time:
1) Sounds like it would fit in easily--I can't remember exactly what Beastmaster gives specifically, but I'm pretty sure that I would allow it, and I know I allow Natural Bond. This is one of your characters from gabrion's campaign that you ditched for Jonas, right?
2) If you want my random thoughts to help you narrow it down, this one seems a bit too Eberron-ish (I seem to remember that there are tribes just like this in Eberron). I don't really have tribes like this that I included, but the Northlands are vast, so I could work in something (and as long as you aren't attached to having whole tribes of dragon-blooded barbarians, a single barbarian who descended from a draconic liaison could absolutely definitely work)
3) Psions suffer from the same issues I mentioned to Keia. However, if you're willing to be hideously emotionally and physically scarred
...I could work with you on a background that would allow a Seer. Oh, and it involves the Far Realms, hence the '
'
4) The Changeling warlock could also work well. Sounds like your character would probably be a loner, but there's information organisations and cabals that he/she could join too if you liked
5) Kobolds are indeed cute--if you pick this one and you find something cool for kobolds in Races of the Dragon come Jaunary, I'll probably allow it...Meepo!
