Deep Aether
Deep Aether is an addon for the original version of The Aether mod. It aims to add lots of new features to give players a chance to venture deeper into the Aether dimension, while also maintaining its original style.
Quick answer
Which Deep Aether release should I use?
Deep Aether 1.21.1-1.1.5.1 targets 1.21.1 with NeoForge. Installation on the client is optional. Installation on the dedicated server is optional. 1 required mod needs a matching file.
Where it goes
Is Deep Aether required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does Deep Aether 1.21.1-1.1.5.1 need?
1.21.1-1.1.5.1. Change the file and its required mods may change too.
Install TerraBlender, The Aether, oωo (owo-lib) first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match. 1 comes through another mod in the chain.
1 extra mod was pulled in by another dependency. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

- Sterling and Chromatic Aerclouds

New Dungeon Loot:

❓ FAQ
Q: Do you plan on backporting to earlier versions?
- A: No we don't. The Aether I Mod only plans releases from 1.19.2 and onwards, meaning this addon cannot reach versions that are prior to that.
- This also includes future unofficial backports and all the legacy versions: our team only disposes of 2 coders that work on Deep Aether as a hobby, and maintaining older versions with a completely different codebase, while also fixing and updating the newer ones in acceptable timescales would be impossible.
- We have no issues with people that want to backport Deep Aether by themselves, letting us know first, and reminding that the backport is not official nor maintained by us.
Q: Where can I get Sterling Aerclouds? I can't find any!
- A: Sterling Aerclouds are found high up in the Aether skies, above Y = 200. If you're playing with a low render distance it might be harder to spot the clusters, but they're there!
Q: Do you plan on adding cross-compatibility with other mods and Aether addons?
- A: Yes, we have already done that with many of the popular addons: Aether Lost Content, Aether Redux, and more!
Q: I am interested in joining your team to help with the development of the mod! How can I do so?
- A: We are always open to accepting new members, especially testers and developers, as well as translators and modelers! (We are however not in the need of texture artists) | You can join our Discord Server and follow the directions for filling out an application in #recruitment-info! BE PREPARED TO SHOW PROOF OF YOUR SKILLS!
