Ice Castle
Java data pack listed for Minecraft 1.21–26.x. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Ice Castles have the same interest as pillager outpost as allays can be found prisonner in them! Those structures can be found in cold biomes and are guarded by green shulkers (they don't loot anything).
Those structures can be recognized because of the giant ice skull above them.
