A spiritual guru on the spectral plane, Wyvern tutors Hopkirk in the art of being dead. It’s Wyvern that teaches him how to use the powers he discovers after his death, from possessing other people to being a poltergeist. If Hopkirk’s having problems in the real world Wyvern will usually have some priceless advice for him. He also has a penchant for poems that almost, but don’t quite, rhyme.
