The Astral Update
The Astral Update is a Fabric equipment mod for Minecraft 1.21.11 that adds new materials, playstyles and gear, along with a set of new ores found in familiar biomes.
What it does
The mod expands the vanilla game with six new materials and three new playstyles, built around classic 3×3 crafting recipes and new GUIs. Skill trees and gear with distinct identities give each playstyle its own progression, and the aim is to offer new exploration and challenges to players who find the base game repetitive.
Strange new ores generate in familiar biomes such as jagged, frozen and stony peaks, as well as frozen oceans and volcanic badlands, and the mod places them deep underground. Aetherite, a sky metal, is scattered across the peaks above Y 130. The mod is described as a total conversion, so its materials and gear take the place of much of the standard progression.
The mod is a client-side only Fabric build for 1.21.11. Players install it alone, and servers run without it. It is released under All rights reserved and is not open source, and the author publishes it under the TheEmpyrean10 name.

What the author says
No one agrees on what to call it. Some say it started with a light in the sky that didn't move like a star should. Others only remember the sound — a distant, rolling thunder that never fully stopped, not for weeks. Burning stone fell across the land like rain that refused to end, scarring hillsides, splitting…
