Nine Lands
Meadows, Blackwood, Swamp, Mountains, Plains, Mistlands, Ashlands — weather, inhabitants and building materials per land, with the transitions between them.

Meadows, Blackwood, Swamp, Mountains, Plains, Mistlands, Ashlands — weather, inhabitants and building materials per land, with the transitions between them.
Eikthyr, the Elder, the Bonemass, Moder, Yagluth: summoning, attack patterns, loot — and what each fallen guardian unlocks.
Load-bearing frames, spans, workbench radius, upgrades up to tier 4. What isn't supported falls — this is where it says what holds.
Crypts and caves are generated from a placed seed with real doors and room chains — new for everyone, but the same for everyone.
