Against The Dark is a collection of mods designed to allow a group of players on a multiplayer server band together and survive in a fantastical world. There is a little difficulty, but its not intended to be overwhelmingly difficult.

This Modpack has a lot of mods, but here is a sample of what you can expect:
Bucolic Origins and Origins: Classes will give you a unique playstyle among your friends!
Alex's Mobs, Untamed Wilds, Ambient Sounds 5 and other mob overhauls bring a living feeling to the wide world.
Dusk and Tough as Nails force players to band together to survive!
Tetra, Archer's Paradox, and more add some spicy nuance to combat.
Pam's Harvestcraft Mods, Farmer's Delight, and more add more options for farmers and expand your potential options for foodstuffs, though keep in mind not all Origins will be able to consume foods.
Engimatic Legacy, Levelhearts, Project MMO, and more provide ways to advance in power.
Immersive Weathering, Immersive Weathering, and Enhanced Celestials add more meaning to the passage of time and movements of celestial bodies.
Artifacts, Reliquary Reincarnations, and Enigmatic Legacy reward players for delving into ruins to uncover lost and powerful relics.
Hexerei, Nature's Aura, Apotheosis, and Forbidden & Arcanus provide multiple ways of pursuing the magical arts.
Yung's Better Structures Mods, Additional Structures, and Repurposed Structures add life and variety to the structures of the world, without going too over the top.
Straw Golem Reborn, Better Iron Golems, and Guard Villagers add more natural defense and utility to allied mobs, without having to invest in big mods like MineColonies.
Snail Mail is the greatest mod in all of creation, and elevates this pack with its sheer glory by letting you deliver mail to your friends with snails.
