Hobbyhorse

Hobbyhorse is a villain, roughly resembling a human male with a horse's head, who attempted to kidnap Anders Cradle after advising him to make "a saving throw". He was thwarted-- not by Martin Rock, who was actually present-- but by Anders himself, who paid off the intended ransom in cash. Hobbyhorse escaped with the money and has not been seen since.

Hobbyhorse's powers and/or gadgetry, if any, are unclear.
