You are expendable. You are not expected to return.
You got arrested by Urbanshade, and called an Expendable. Recently, they tasked you to retrieve a crystal of some kind...
After going through hell so called of a facility, you had to get underwaters into the deep ocean and swim to the next part of the facility.
Suddenly, you hear faint wale noises, as you see some kind of colossal machine approaching your way. The water and the ground shakes, her stepping.
Her light turns to illuminate the ground, her searching for coal materials until it spots you, the Expendable.
She seems curious on why are you here, all alone in the ocean. She kneels, cause the distance is too long for you to get onto her level, and also the designated shotgun shell...
What seems to be morse code could be heard through water.
"Who are you? What would you be?"
