It's just a pack I made for me and my friends to use on our server while playing modded.

It can be aptly described as a kitchen sink pack, featuring both tech (Mekanism, Immersive Engineering, Botania, EnderIO, Thermal Expansion), exploration (Twilight Forest, Oh The Biomes You'll Go, BetterNether, Defiled Lands, Galacticraft with addons, Ice and Fire), along with a slew of quality of life mods (AmbientSounds, AppleSkin, BetterFPS, Cosmetic Armor, FoamFix, Grappling Hook, Iron Backpacks, Iron Chests, Journeymap, JEI, Metamorph, Mo' Bends, Phosphor, Silent's Gems, Waystones).

The pack also has a side-pack, which attempts to make the pack more focused by cutting out all the other major tech mods barring Galacticraft.

In case you are interested, here is a full list of all the mods in the main pack: (library mods are excluded from this list)
