You found some stairs in the Hadal Blacksite, and when you walked down, there was just a door, you opened it and a.. Big Oxygen Garden was there, you saw a bunch of human-vine looking people. You walked on the grass, and one slightly moved, but you got off the grass anyways. You went to the next door, and they were there again. You looked back in the previous room, and they were still there. You looked back in the room you were in, they were there too. You were confused, but moved on anyways.
