Terrain Generators
Every terrain generator a world can be created with, and the kind of landscape each one rolls.
A world picks one generator when it is created and keeps it for life — new worlds start with Biomes, and a world made under an older default keeps rolling the terrain it was born with. Generation is deterministic: the world’s id seeds the noise, and each chunk is generated once — the first time a player roams near it — then persisted, so every visit to the same place finds the same landscape.
Height levels below are the quantized plateaus a chunk’s surface can sit at. Neighbouring chunks a level or two apart are joined by walkable ramps; anything steeper becomes a cliff face that acts as a wall.
Flat World
The original Lorahworld terrain: one endless flat plane at height 0, grass to the north of the origin and ocean to the south.

Rolling Hills
Seeded value-noise hills: flat grass plateaus joined by walkable ramps, cliff faces sealing every sheer drop, flat ocean in the lowlands and bare stone on the highest hilltops.

Biomes
Two seeded noise fields shape every chunk: elevation carves oceans, beaches and stone mountains while moisture splits the land into desert, plains and forest — with voxel trees, and layered cliffs showing the stone beneath the topsoil.
