The Exogin (sporizatus vermis) is an otherworldly parasitic worm that causes discoloration, minor deformation and dark veins to form across half of its host's body in its first stage of infection.
Unfortunately, Ophelia became the victim of one. If not treated as soon as possible, it may become irreversible. Proceed with caution; even in the first stage, the host can be rendered as highly aggressive towards other living beings - especially any alternatives of itself.
