biography
John Harrison was personal assistant for Joseph Serf who was forcing the Skullions to make the Hologram work correctly. Harrison knew that Serf was a hologram, however he wanted to make profit by selling the SerfBoard to everyone using Serf's hypno power. Harrison's pen transmitted an electric shock to all Skullions if they incorrectly moved Joseph. It is unknown what happened to Harrison when he got transported to the Skullion Ship. He presumably got set to work by the Skullions and treated badly.
