It's a sketch of one of your two ORIGINAL CHARACTERS. This one is called FIGMENT.
He's a nightmarish construct birthed from the psyche of your other character, ABEL. Kind of like an imaginary friend, only he is very real and doesn't really act like much of a friend at all. They are supposed to be mirrors, somewhat, and have certain parallels in the ways that they behave and carry themselves.
You got the idea after you first arrived on PROSPIT.
