[@Klomster]Yes. I'm still awaiting ruling on population, but I doubt it would support anything like that. I'll clarify that they're large (not giant) for sheep, but small for the takhal. There are more anatomical differences for flavor, pending GM opinion I will probably add to sheet. 

But, I'm not sure how else they'd make clothing, or their mobile shelters except by some livestock (which require leather at the least). *I don't think GM would begrudge me glorified teepees, that's certainly stone-age technology. On that note, an alternative is that they hunt some bison-like creature (Ovis), which I'd be fine with but since they aren't carnivores, I didn't imagine them as the hunting type.

*I've removed the wool aspect, on researching the timeline of wool use in human history they'd probably be a few centuries away at least from manufacturing any textiles from the aad's wool. 

*Makes me wonder how much time will pass between turns, on average. If it's whole decades or centuries, this little story will probably be a simple snapshot of this time period. I am planning on having it directly precede a big schism in takhal society that creates multiple tribes for the first time. I suppose it is only the introduction. Eh, is that a spoiler? Oh well

*None of the pre-existing herbivores really fit the bill for what the takhal needed in the case they don't hunt. Interesting consideration: No hunting, no need for bows. Weapons are a given, there's bound to be some infighting occasionally. Good justification for balance, if needed. Still, you need to defend from predators, I imagine there are a lot of wolves on the steppe (/grassland). That would be justification in the other direction
