Let's Burn Up a Character

I bet you thought I'd forgotten about this.
...and you were right, I did! But now, I remember. Better late than never, right? ...right?
So anyway, here's what we've got:

Beliefs
1. Not sure why but damn I hate wizards. Gotta run them out of town/country/continent!
2. Oleg is precious. I will do anything to protect Oleg. Even if it means giving up possessions. Even if it means I have to give up my own life.
3. I will get the Krundlehorn back, and then use it to ruin my brother!

Instincts
1. Always scope out a new place before going in.
2. Never walk into a deal without a bribe.
3. Never let slip secrets, not even when inebriated.

So that's almost a complete character, right there, except we never did get that oath. I know it's been a year... er, 16 months, but if anyone wants to toss in some suggestions for a good Oath Belief, that's be cool. It has to be something our dwarf swore to one of his relationships:
- His brother, the master hornsmith who created the Krundlhorn.
- His offspring, born of wizard rape. He repressed his memory of the incident, but adopted the child anyway.
