Deep Dark Dimension
by kramsdell
Deep Dark Dimension, a Fabric mod for 1.20.4, adds a dimension built around the ancient city and its warden boss.
What it does
The mod adds a dimension that players reach through a portal after locating an ancient city with the locate command. Entering it requires clearing sculk veins from a reinforced deepslate rectangle and lighting the portal with flint. Once inside, warden ore is mined with a netherite pickaxe, and silk touch yields the remaining blocks. Deactivated tools can be crafted from warden scales, and the returning portal is lit from its corners with a deactivated warden pickaxe.
Defeating the warden boss drops a warden's heart. Every player and the server need a copy of the mod. The code is open source under the MIT License, and the public source code and issue tracker are linked from the project. Files exist for 1.20.4 only, with 1.1.0 as the latest Fabric file, published on 2025-07-26.
