Starting Tribes & Biomes *(from the original brief - preserved)*

Tribe Region / Biome Spiritual Bias Mechanical Influence
The Corani The Whispering Fens (coastal marsh, mist) Deep aquatic & subterranean Fae Immune to rotspores; extreme vulnerability to iron
The Fir Domnann The Iron Crags (barren mountains, slate quarries) Earth elementals & forge spirits Smithing & resilience bonuses; regional spirits demand blood sacrifice for passage
The Tuatha de Danann The Sylvan Canopy (primordial old-growth forest) High Solar courts Direct line to Fae nobility; cursed with high physical fragility

Tribe sets initial world-state, spiritual alignment, and ancestral vulnerability. In multiplayer it also becomes an economic specialisation (The Sacrifice Menu).
