In the lore of Demesne (/dəˈmān/) the Overworld of Minecraftia is crisscrossed with ley lines, flows of magical power. When these lines meet a demesne is formed and the power of the land can be tapped into by building the proper structure on the point of crossing. That energy can then be used to fuel magical machines, rituals and totems.
The alpha for the Fabric loader version of Demesne is out! It requires the Fabric API and Cotton, these dependencies are for the Fabric version only.
Also the Fabric version has a slight different look from all of my videos and screen shots (no obj loader for one thing) and isn't done so there are some things from the forge version that I haven't added yet (spirit summons, a few totems.)
Here's a video on getting started with the mod:
