Ellington was born to an aristocratic family of Hillsbrad. As a human, Ellington never worked a day in his life. He was spoiled thoroughly by his parents, since his older brother Haplo was cast out when he was young, leaving him as the only child and heir to his family's fortune. This lead to the development of his very rotten and snobbish attitude. Along with this haughty personality, Ellington was involved in other shady business of the rich and gaudy lifestyle, and had no time for those he deemed "lower peons."
When his family's mansion was stormed by a scourge raid, Ellington was reborn into the legion of undead. He developed a newfound hatred for the Alliance, obsessing over the fact that nobody was there to protect him when his family was attacked by the Scourge. Though he has used his hatred to become a skilled rogue, he is continually driven insane by his position as an undead, and his personality has become manic.
Ellington is also the star of many bizarre comic drawings by Ellington.
