A Modpack with over 150+ mods, specializing in a world with a variety of monsters, cool locations, and most importantly, magic.

Contains all the essentials for every modpack (Backpacks, JEI, Appleskin, etc.), but also includes things such as

Mana and Artifice; an incredibly complex but very cool magic mod
Iron's Spells and Spellbooks; a less complex but very cool magic mod
Sons of Sins and Biomancy 2; necromancy, and just a bit of fleshy interiors
When Dungeons Arise; enormous randomly generated dungeons
Alex's Mobs, Critters and Cryptids, Mythic Mounts, Monsters and Mushrooms, Blood and Madness, and Critters and Companions; varied mobs to find out in the overworld
L_Ender's Cataclysm for those sweet, sweet boss fights
Minecraft Comes Alive; have your own village to manage
Vampirism; become a vampire and gain special abilities
TARDIS
and more!

I put a lot of time and effort into this one and really like how it turned out. Hopefully you can enjoy too, if you've read this far.
