Wookies meet dwarves. Mean, aggressive, scrappy, not evil. Territorial and clannish.
Part of a vast Underdark realm. Mineral rich. Bulky creatures with low center of gravity.
Centuries of clan fighting and nomadism has given rise to uneasy borders, ritulastic rules for life and combat and law. Bloodprices enforced.
Closest to a king is a clan elder who rules and decides for their kin.
Life is hard. Unkind. But honor given and respect granted is sacrosanct.
Animists and ancestor worshipers. One important Spirit, The Burrower, is venerated and placated as a representative of the danger of the caves and deep dark.
