The Ceilands

The Ceilands adds a new dimension built around whimsical surreal adventures. Its unusual proportions come from the bedrock ceiling and bedrock floor that enclose it, and most of the dimension's bulk sits near the ceiling, made of a blue-tinted stone type. The mod keeps vanilla aesthetics intact, so the new terrain and content fit inside the existing style of the game rather than replace it.

Access starts with a hint that appears when a player first acquires an Echo Shard. A portal frame is found in Ancient Cities and built from Reinforced Deepslate, and the Ceilands Portal Activator is crafted to light it. Five biomes are included, among them an icy overhead terrain and a floating forest, along with a few structures such as Ceillages, Hanging Castle and Ocean Cubes. Custom mobs and bosses appear as well.

Two new wood types, Ceiltrunk and Luzawood, are included. Ceiltrunk trees grow only from the ceiling, while Luzawood grows from the ground like vanilla trees, and both produce the same range of wooden products as other vanilla wood. The Ceilands is installed on both client and server, so the server and every player need the mod. Files are published for Fabric, Forge, NeoForge and Quilt across five release versions, 1.19 – 1.21.1, and the code is open source under the MIT License.
