Northbound

Northbound changes the world generation of Minecraft so biomes sit according to their latitude north or south of spawn. A spawn point is set in a temperate region, typically plains or forest. Heading north from spawn, a player passes through colder zones like dark forests and taigas before reaching a polar region of snowy biomes. Moving south leads first through arid biomes like deserts and badlands, then into a tropical zone with jungles and mangrove swamps. The climate zones repeat across a map that is centered on spawn.

The mod is built on large biomes, with climate zones repeating roughly every 16,000 blocks along the Z axis across a span of about 65,000 blocks. The mod runs alongside the standard world types, covering default, large biomes and amplified generation without conflict. Northbound is known to work with Terralith, Biomes O' Plenty and Continents, and compatibility is developed for Tectonic. It is not compatible with every mod that changes terrain generation, so mods that alter terrain may conflict. The mod runs on a server, and players may add it on the client, but it must be present on the server.

Northbound is published for Fabric, Forge, NeoForge and Quilt, and as a data pack for Minecraft 1.20.1, 1.21.1, 26.1.2 and 26.2. Files for 26.2 are the latest and are on the beta channel, released 2026-07-29. The mod is released under the Creative Commons Attribution Share Alike 4.0 license and is not open source. Concurrent Chunk Management Engine is used here, and it corrects an ordering problem that Northbound depends on during vanilla world generation. Files exist for all four loaders.
