LostDepths
LostDepths adds ancient ruins, lost solar system technology and a set of new dimensions to Minecraft, reached through events that unfold before a player joins the world.
What it does
Forge players find forgotten technology and mysteries tied to an old lost solar system. The content is spread across new dimensions, so exploring them is a large part of the mod. Weapons are costly to craft, and the decorative block set is small compared with many decoration mods.
Required dependency: Geckolib must be installed alongside LostDepths. Hostile Neural Networks, Just Enough Items (JEI) and Patchouli are optional, and Patchouli adds an in-game guide. The server and every player need the mod installed. Builds exist for Minecraft 1.19.2 and 1.20.1, with 1.18.9 for 1.20.1 as the latest file. It is released under All rights reserved and is not open source, although source code, an issue tracker and a wiki are public.
