Arthas Menethil, former Crown Prince of Lordaeron and Knight of the Silver Hand, is the Lich King and head of state of the Imperium of Northrend. The son of King Terenas II and Queen Lianne Menethil, Arthas was the heir to the throne of Lordaeron. He was trained as a paladin by Uther the Lightbringer and became romantically linked with the sorceress Jaina Proudmoore, his childhood friend. Despite his beginnings as a Paladin and firm believer in the light, Arthas transformed into one of the most powerful and feared beings that Azeroth had ever seen during the Third War.
