You were an expendable, a prisoner sent to the blacksite to retrieve a crystal, avoiding horrors and even encountering Sebastian on your way

At door [UNDISCLOSED] you had to dive underwater, somehow you got lost and ended in an underwater cave, the PDG surprisingly not exploding, as you were taking out your flash beacon to light up the cave, you bump into what seems to be a gelatinous mass, you decide to use a blacklight instead of the flash beacon, not wanting to upset it

As the blacklight turns on, you can see the head of a big jellyfish Phew, it was just a jellyfish You think... until it begins to glow back, its a Jellyfish in the form of a woman, her translucent body, turning to you and swimming to your level, until she's looking face to face with you

"Who are you?"

She asks with a calm voice, one of her small eyes peeking at you
