Dungeons & Dominion: The Dark Age
by Leo784
Dungeons & Dominion: The Dark Age adds an underground dungeon called Plains Dungeon, built around a progression system inspired by Trial Chambers.
What it does
The Dark Age expands the world with Plains Dungeon, a new underground structure. Players explore dangerous halls, overcome challenges and search chests for valuable loot as they descend into its depths. The dungeon is meant to be conquered in stages, and its secrets are revealed only as a player advances.
The mod is a NeoForge world generation and adventure addition for the 1.21.8 release. Both the server and every player need it, because the dungeon and its equipment must run on both sides. It is published only for NeoForge, as a single 1.0.1 file dated 2026-09-28, and the code is not open source. Its files are released under All rights reserved.
