Xadune: Fantasy at its Finest is designed around magic, fantasy, and creating really wacky machines. This contains additonal creatures, additional ores, and SO many biomes!
You can become a fantastical creature like a werewolf or a enderkin(deceded from an enderman) and have unique traits based on your origin. You can make vast computer systems with Applied Energistics and even wilder contraptions with the Create mod. If you're the fighting type we've got dimensions and dungeons and glory, or if you want to explore we've got biomes and ruins and even other planets! Last but definitely not last we have mythical mounts to help your adventures go smoothly from giant 4 legged sea slugs to giant fire birds, there's bound to be a mount to make you squee!
Example mods contained within:
Create(and addons)
Mimics
Applied Energistics
ComputerCraft
and copius magic mods that will take me forever to name.
So please have fun with it!
