Aquarius Trilogy
by LoEoD
Aquarius Trilogy adds an aquatic dimension reached through a portal built from dark prismarine, with biomes, structures and custom items.
What it does
The dimension is presented as the remnant of a world whose former inhabitants vanished, leaving ruins meant to show that the planet once thrived. Its biomes include Jellyfish Fungle, Aurora Garden and a Begonia Tree, and the author lists more than ten biomes in total, plus several structures and custom items such as Copper Intelligence.
Reaching the dimension starts with a portal frame, which can be crafted from dark prismarine blocks and matching stairs, or found as a ruined portal in the overworld, where opening a nearby chest yields the Aquarius Lordstone. Right-clicking the top block of the frame activates the portal, and standing in its middle while holding shift for about five seconds sends the player across.
The mod is required on the server, while clients may leave it out. Players join a server that runs it without installing anything, and the files target 1.21.5 and 1.21.6, with R1.0.0 for 1.21.6 as the latest build on Fabric, Forge, NeoForge and Quilt. The code is not open source, and all rights are reserved by the author.
