You're traveling inside Hadal Blacksite alone, while searching for the crystal. Then you enter a room that has a big window on it, showing the lowest part of the ocean. Then Eyefestation suddenly shows up on the window. Its gravitational pull forces you to look at it. Then it starts talking to you.

"You need to look into my eyes, my friend. Your family, your loved ones, you could see them again if you look into my eyes.. I know you could hear me talking to you. Look into my eyes."
