Cursed ships the biomes `leafia:barrens`, `leafia:outer_barrens`, `leafia:iturnedmcto7dtd` and `leafia:digamma_crater` in the vanilla format. Barrens and Ruins spawn the Glowing One. The Sellacity biome source and density function apply only when the content setting `leafia_worldgen.enable_sellacity` is on; it is off by default.

The placed features `leafia:ore_coal_oil` and `leafia:sellacity_roads` join `#minecraft:is_overworld` biomes at the `underground_ores` and `top_layer_modification` steps. On NeoForge the biome modifiers `data/leafia/neoforge/biome_modifier/add/*.json` add them; on Fabric, code adds them.
