Bygone Fortress Plus
by Cassian
Bygone Fortress Plus reworks the vanilla Nether fortress into a larger structure, ported from the original Bygone Nether fortress for newer game versions.
What it does
The mod overhauls the vanilla fortress and gives it a grander scope, carrying over the fortress that first appeared in the Bygone Nether mod. Fabric API is required on Fabric, and the mod runs on client and server, so both the server and every player need it. Builds cover 1.20.1 – 26.2 for Fabric, Forge and NeoForge, and the code is open source under the MIT License.
