Just worth noting that the 'tribes' listed are actually tribal nations rather than single tribes. They consist of anywhere from a handful of pathetic bands (Kabloqui) up to dozens of large tribes (100's of individuals) with tributary relationships (e.g. Kubora, Hodiri, Tulwyn). Some of the nations have ranges that encompass a variety of environs, so you might have a mixture of coastal, forest and hill tribes. Characters with farming/herding/domestic backgrounds may well be (escaped?) slaves.
My initial thoughts on possible groupings: -
- Primarily fisherfolk = Adaenum, Chymak, Kamaki.
- Primarily forest folk = Anoa, Taelda, Tulwyn, Ymodi.
- Primarily horse tribes = Chelni, Hodiri.
- Primarily hill tribes = Kath, Solori.
- Primarily degenerates = Kabloqui (weak), Pagaelin (strong).
- Forest/Hills = Bujoc
- Forest/Hills/Coast = Equani (slightly degenerate/strong?), Gozyda (3 small sub-nations, 1 degenerate/weak), Kubora, Urdu.
