Grand Depths
by LIK87
Grand Depths is a Forge total conversion for 1.20.1 that adds a new dimension reached through a start chat command, filled with vanilla-style mobs and items.
What it does
The mod is a total conversion set. Its main addition is a new dimension of its own, with mobs and items that build on the vanilla game rather than replacing it. Players enter the dimension by typing the start chat command, so the entry point is an explicit action rather than a portal found in the world.
Because the mod changes a large share of the game's content, it runs on client and server. Both the server and every player need it installed. Grand Depths is built for Forge only, with a single build for 1.20.1, released as 0.0.2 in the beta channel. It is not open source and is released under All rights reserved.
Key features
A new dimension
A separate dimension added to the world, reached by typing the start command in chat.
New mobs and items
Creatures and items that sit alongside the vanilla set, expanding what players meet in the dimension.
Custom sound effects
The mod ships sounds for impacts, rock debris and combat, drawn from several sound packs credited by the author.
Armor models
Armor pieces with custom models; some of them conflict with OptiFine, so the author recommends disabling the optional OptiFine features that clash with them.

Kingdoms & Dynasties: Revisited is another Forge 1.20.1 client and server mod, released under All rights reserved, which makes it a closer match on licensing.
