Regarding last update: I'm not sure if I'm going to keep the Liyap'ti milk consumption. There's very little on the Incas' milk consumption and even though alpaca milk is safe to eat they don't produce as much of it as cows (and obviously real-life armadillos produce much less).
And since the Chak'tu are native to Uraliwa only (for now) either they would have started being milked at most 100 years ago, or the Liyap'ti would have had domesticated another animal in their homeland which is a pretty big stretch.
Of course I'm not doing a 1-to-1 with the real life inspirations but still, it feels like I'm pushing it.
I should probably make a blog section for things like this.
