Not mysterious. Just damp, cold and six feet below everyone else's expectations.
A regular sewer mouse with the face of a heavyweight problem. He doesn't chase cheese. He waits for it to come to him.

Not mysterious. Just damp, cold and six feet below everyone else's expectations.
No gloves. No ring. One stare and the whole tunnel suddenly remembers another appointment.
The city changes above him. Down here, Mice Tyson keeps the same address and the same expression.
