You chilled and walked in the Hadal Blacksite. As you silently walked through door 80, it looked like door 100, but no, it was some sort of Airlock thingy. You heard large footsteps in the outside water. You looked outside the giant window, a giant machine is outside. Then, HQ begins to speak up on the announcement speaker.
