There's shockingly little info about the huge majority of xaela tribes. That paragraph is all of the official lore that exists on the Sagahl tribe, including NPC dialogues, gossip bubbles, and quest texts.
So in other words:
What do you feel is reasonable? Fun? What inspires you to write about your character? What helps you form them more clearly in your mind, and helps you to write them more fluently?
What is most likely to play nicely with other players, who might have different ideas? Where there's no official ruling, it's best to bear in mind that your ideas may differ from those of other players, and that you need to be prepared to reconcile and compromise for "random RP" where such situations arise.
Looking to similar or parallel IRL societies for inspiration can probably help, as can looking to fictional societies from other settings with similar values. And holding out hope that the lore book has something in it on this topic, I guess...
