In the World of Greyhawk campaign setting for the Dungeons & Dragons roleplaying game, Tenser is an archmage who strives to rid the Flanaess of evil. Tenser is a former member of both the Citadel of Eight and the Circle of Eight. In Dungeons Age of Worms adventure path, Tenser is referred to as "Manzorian". Creative origins Tenser, an anagram of "Ernest", was initially a wizard player character created and played by Gary Gygax's son Ernie, one of the first two characters that played the game now known as Dungeons & Dragons. In the fall of 1972, Gary Gygax was working to create rules for a new type of game based on a demonstration he had been given by Dave Arneson. In order to provide a playtest environment in which to develop these rules, Gygax designed his own castle, "Castle Greyhawk", and prepared the first level of a dungeon that lay beneath it. Two of his children, Ernie and Elise, were the first players, and Ernie rolled up a wizard, Tenser. During the evening, the children fought and destroyed the first monsters of the Greyhawk dungeon; Gygax recalled this as either being some giant centipedes or a nest of scorpions. During the same session, Ernie and Elise also found the first treasure, a chest of 3,000 copper coins (which was too heavy to carry, much to the children's disappointment). After his children had gone to bed, Gygax immediately began to work on the second level of the dungeon. The next night, Don Kaye and Rob and Terry Kuntz joined in, rolling up the characters Murlynd, Robilar and Terik respectively. In the following weeks and months, Tenser often adventured with Robilar and Terik. At one point, using their combined forces of loyal henchmen, the three controlled access to the first level of the Greyhawk dungeons while they ransacked the lower levels. Eventually Tenser became the second character to reach the 13th (and at the time, the bottom level) of the Greyhawk dungeons, when he noticed that Robilar was missing and went in search of him. Gary Gygax "borrowed" Tenser's name for two spells, Tenser's floating disc and Tenser's transformation. When Gygax was forced out of TSR in 1985, he lost the rights to most of his characters, except those that were anagrams of his own name. Tenser is one of the famous mages whose spells were included in the 1988 Greyhawk
