This is a modpack made for the private server ESK SMP that overhaul every structures and the biome generation. There are also new dimensions like Ratlantis or The Midnight. You will also find magic and technology mods and some rpg elements.
If you like magic and witchery, we have a few mods like Hexerei which allows you to brew strange ingredients and perform rituals. You can also practice necromancy with Sons of Sins, make alchemy with Theurgy or manipulate the arcanes with Forbidden and Arcanus.
On the other hand, if you prefer diving into technology, you can program your own robots with computer craft or industrialize your village with Create, Immersive Engineering or even Mekanism.
There are a bunch of other mods to either add quality of life or a little bit of spice to your world.
