 Noble would work but I can't help feeling there's a better adjective that has more of a 'lawful evil' flavor... Machiavellian, refined, aristocratic? I'm not sure, if you can't find one, no big deal. I understand what you're going for and that's what matters.

I think Machiavellian would be a good adjective for it (it apparently is also one of the dark triad personalities).

For the skill, I put tracking, as Joras was taken on numerous hunts for his father, although I"m sure he'd have preferred to hunt a different prey.
