Gandalf, named after the wizard protagonist of Lord of the Rings, is a member of the Gamers, one of the factions of Bobs described in Heaven’s River.
His Virt presence is the likeness of the LOTR character, and his VR environment is modeled after Orthanc, from the LOTR movies, but with La-z-boy couches.
He represents the Gamers on the project to rescue Bender.
