Who is Darth krayt?

Darth Krayt, born A'Sharad Hett, was a Human male who served as a Jedi Master in the waning days of the Galactic Republic. The son of legendary Jedi Knight Sharad Hett and his wife K'Sheek, both of whom lived among the Tusken Raiders of Tatooine, he eventually became the Padawan of Jedi Masters Ki-Adi-Mundi, and later, An'ya Kuro. When he was only a teen, Sharad Hett was murdered by the Jedi assassin Aurra Sing, who was later defeated in a duel by a young A'Sharad Hett. During the Clone Wars, he served the Republic as a General and established himself as a charismatic leader who often led his troops from the front. He eventually became friends with the young Anakin Skywalker and helped Anakin come to terms with the destruction which had been wrought by the galaxy-wide war. A'Sharad took part in key conflicts during the war such as the Battle of Boz Pity and Siege of Saleucami. He managed to survive the Clone Wars, and was one of the few Jedi known to have escaped the Great Jedi Purge in 19 BBY.

"I have been through death and conquered it. I have returned with my power multiplied. The dark side of the Force lives and manifests itself through me! I reach into the dark side now and send ripples through it to all who serve it-know that I live!"―Darth Krayt, Dark Lord of the Sith[src]
