Mystmere was created for my multiplayer server with exploration, farming, magic, immersion and roleplaying in mind. All mods fit into a medieval theme. There are new dimensions, an overhauled overworld, new mobs, animals, trades and more. Different shaders for both strong and weaker computers are included, as well as resource packs with overhauled animations. 

It has also been optimized and includes performance enhancing mods without Optifine.
