A 1.21.1 Neoforge Create based tech modpack with an emphasis on travel and world-building from Create:Aeronautics through the use of various tweaks. Strong, or otherwise overpowered items and mechanics have been removed, this includes villager trading, elytras, and the transmutation table (from Alex's Mobs), in an effort to slow the early game, and make the endgame not so trivial. Other notable mods include: Corpse, Create: Big Cannons, End's Phantasm, Farmers Delight, Quark, Sophisticated Backpacks, Storage Drawers, Supplementaries, Terralith, and Vista. A full mod list is below.
