Tropical World
by KURONAMI
Tropical World replaces the overworld with a single warm sea, so a new world begins as open turquoise water scattered with sandy islands.
What it does
Generation is reshaped so the whole overworld becomes one sunlit tropical ocean. Raising the sea level to the surface turns the continents into a scatter of sandy islets and an archipelago, yet the vanilla biomes, ores, structures and mobs keep generating as they normally do. Hidden larger islands hold oases of clear water pools ringed with grass and reeds, and palm trees are placed only on flat dry ground.
The mod is a server-side only addition, so players join without installing it and only the server runs it. It requires Isekai API, which supplies the worldgen framework the world is built on, and it is released for NeoForge 1.21.1 only. Sister worlds by the same author cover other terrain types. The code is not open source and is distributed under All rights reserved.
Key features
All-ocean overworld
New overworld terrain is a continuous tropical sea with sandy islets in place of continents.
Hidden oases
Rare oases sit inside larger islands, each a water-and-palm set-piece that spawns only on clean interior ground.
Vanilla content kept
Ores, structures, biomes and mobs still generate, so the existing game content stays in the sea world.

Use cases
Island exploration
Players who want a world made of scattered islands and open water can start a new world and sail between sandy islets to find oases.
Who it’s for: Server owners and players looking for an ocean-only overworld on NeoForge 1.21.1 will find the terrain the mod generates useful for a fresh survival or adventure world.
How it compares
IslandGen is a NeoForge mod for 1.21.1 that runs on both client and server, and it is not open source. Angel Islands works on Fabric, Forge, NeoForge and Quilt for 1.20 – 1.21.10 with only the server needing it, and it is open source under the MIT License.
