IslandGen
by Mainsteam115
IslandGen generates islands across the world, including a few that hold loot, a stronghold portal and a small survival starter.
What it does
Islands appear at random throughout the world, so a player may find one while crossing open ocean. Some are simple prebuilt survival islands, and others hold a starter hut, loot barrels, wrecked ships and hidden rooms. A configurable stronghold portal is also part of the generation. The mod is published for NeoForge 1.21.1, with the latest file 1.0.3, and it runs on client and server, so both sides need it.
