Warm Islands

Name: Warm Islands
Author: e3l3rno

Warm Islands adds tropical islands, pirate-themed structures and a vast ocean to worlds that generate with it, and players who explore the seas find the new terrain first.

FabricForgeNeoForgeQuiltServer required, client optionalGNU General Public License v3.0 only1.19.4 – 1.21.3

What it does

The mod generates warm islands in the ocean. Small islands often appear in groups, while bigger islands stand alone and break up the open water. Pirate-themed world generation places pillager outposts, villages, ruined portals and jungle temples on the islands, so exploring the seas leads to varied landmarks.

A generate.warm island option appears in the world type tab when a world is created, where it can be chosen over large biomes or superflat and otherwise works the same way. The mod adds nothing else beyond the terrain and its structures. The server must run it to generate the islands, while players may leave it out. Builds exist for Fabric, Forge, NeoForge and Quilt across 1.19.4 – 1.21.3, and the data pack option covers server platforms that do not use a mod loader. The code is released under the GNU General Public License v3.0 only and is not open source.
