I’m really happy to see all these ideas! I’ve actually been trying to draw out multiple types of villages these snow mares would possibly live in. I’d imagine that depending on the resources available, their houses would be different. In regions with very little trees, they would mostly make an igloo village like this and have to depend more on fish. They could even have seals as pets.

A snowy wooden village and a possible ice village is in the works currently. I’ll update with that later. Keep up the great ideas!
