Miles Teg is a fictional character in the Dune universe created by Frank Herbert. In Heretics of Dune Miles Teg is intoduced as the former Supreme Bashar of the Bene Gesserit Sisterhood. He is charged with the weapons training of Ghola Duncan Idaho by Taraza the Mother Superior of the Bene Gesserit. His mother Janet Roxbrough, a Bene Gesserit, taught him some of the ways of the Sisterhood before he was sent to Lampadas to train as a Mentat. He was later put under the foreign "T-Probe" that the Lost Ones returned with, his mentat abilities learned the T-probe before it could learn him, and this created a deadly reaction within Teg. He was able to move faster than the eye could see, at the cost of incredible energy expenditure, he had to consume huge amounts of carbohydrates to regain his energy. At the end of the book, he sacrificed himself on Dune as the Honoured Matres turn it into a charred ball. At the beginning of Chapterhouse: Dune a Ghola of Teg was birthed, where the Bene Gesserit reawakened him to his full memories. Under the intense stress of the T-probe, Miles Teg's latent Atreides abilities were unlocked, he moved with blinding speed, had a unique form of prescience, could sense immediate danger from people, and also had the ability to see no-ships.
