Castles And Outposts
by kilkavakilka
Castles And Outposts adds medieval castles and smaller fortified outposts to world generation, with Vindicators guarding the structures and their treasure.
What it does
The mod places large medieval fortresses with multi-level towers, tight corridors and hidden rooms, along with smaller military camps scattered across biomes. Structures are generated in the world, so players meet them while exploring instead of building them by hand. Abandoned and inhabited structures both appear, and the Vindicators inside are well armed, so players should prepare armor and weapons before heading out.
The fortresses are meant as dungeon-style goals: players can defeat the guards, clear rooms and claim a structure as a base. Generation is set up to blend with vanilla biomes and to work alongside other structure-generation mods. The mod runs on Fabric only, on client and server, and Fabric API is required. Files target 1.21.8 only, with 1.0.1 as the latest build, released 2026-06-06 under the MIT License. The code is not open source.
