I've read that moon elves, for example, don't want to get involved with wood elves precisely because they don't want to place their feelings where they know it will be impermanent. Halsin also fits into the canon of the wood elf because he has these qualities, he is calm and balanced. Of course, I do not rule out that I define the entirety of his character by his origin. But I don't see anything wrong with that. He's a wood elf and he's a cool character, I don't quite like poly, but nothing is perfect.
