Arthas Menethil

Arthas Menethil, Crown Prince of Lordaeron and Knight of the Silver Hand, was the son of King Terenas Menethil II and heir to the throne. He was trained as a paladin by Uther the Lightbringer and was inducted into the Order of the Silver Hand. Arthas also had a romantic relationship with the kind sorceress Jaina Proudmoore. Committed to the protection of his people, Arthas was determined to stop the plague spreading throughout Lordaeron. Despite his promising beginnings, Arthas became one of the most powerful and evil beings Azeroth would ever know. Although he killed the necromancer Kel'Thuzad, Arthas was unable to stop the spread of the plague and resorted to increasingly desperate methods, such as purging the city of Stratholme.
