You find a hidden cave in Shifty Shafts that takes you between the islands...where The Watcher, a friend of The Seven, has been moving the Zero-Point through the multiverse to hide it from The Order. Your activity here starts to cause the Zero-Point to split into pieces. To return to the surface you complete quests, forage for mushrooms, mine ore, get gear to take on boss battles, and help The Watcher reunite the Zero-Point to find your way home...and help a few others find rest in the process.
