Therion Gers (later Therion the First of Gers) was the human friend of Nether the Younger, one of the earliest rulers of Netheril. When the humans of Netheril began trading with the Earlanni elves, Therion became the first to learn the ways of magic, and after around a year of training, was able to cast the magic necessary to start a fire. Two years later, he had risen to the third most important position in Netheril, after Nether the Younger and the shaman Spiritsummoner.
