Stellaria
by Le_Keko
Stellaria puts players into a space-like dimension where they fight a dragon-like boss, Zregos, and its minions.
What it does
Stellaria is a Fabric mod built around combat in a space-like environment. The dimension is reached through a portal that players craft in the late game, and the fight takes place inside it. The mod's only boss is Zregos, which is supported by three minions, and the author intends to add more bosses later. Players can only leave the dimension through death or victory, and the dimension keeps their inventory automatically, so items are not lost when they die there.
Boss fights use custom clouds and a custom shader that some computers may find heavy. A config option lets server owners and players change the rendering quality. Stellaria runs on client and server, so both the server and every player need the mod. It requires Fabric API, Geckolib, MidnightLib and Veil, and it is released under the MIT License. The source code is public, and the mod has been published for 1.21.1 only, as the 1.0.0 alpha file dated 2026-06-29.
Key features
Space-like combat dimension
A dimension built for fighting enemies in a space-like setting, entered through a portal crafted late in the game.
Zregos and minions
The current boss is Zregos, the Crystalius Cosmic Spider, which is protected by three minions that guard the arena.
Keep inventory in the dimension
Items are kept when a player dies inside the dimension, so losing gear to the fight is avoided.
Custom boss visuals
Boss fights render special clouds through a custom shader, and a config option adjusts the quality of these effects.
