Overview
Arthas Menethil is a fictional character who appears in the Warcraft series of video games by Blizzard Entertainment. He was once a paladin of the Silver Hand and the crown prince of Lordaeron, but he was corrupted by the cursed blade Frostmourne in a bid to save his people. He later became the Lich King, one of the most prominent antagonists in Warcraft lore. Arthas also appears as a playable character in the crossover multiplayer online battle arena game Heroes of the Storm. The critical reception of the character has been mostly positive.
In Warcraft III, Arthas is voiced by Justin Gross. In subsequent appearances, he is voiced by Patrick Seitz (paladin and death knight Arthas) and Michael McConnohie (Lich King Arthas).
Development
According to Warcraft game designers Scott Mercer and Greg Street, "early on in the development of Warcraft III, we knew the game would be about heroes leading their armies into battle. We initially created Arthas as one of those leaders, so we knew from the beginning he would be central to the storyline", and that he "is the bridge connecting the human and the undead campaigns."
Regarding the development of World of Warcraft: Wrath of the Lich King, Mercer stated that "when development began on Wrath of the Lich King, we knew we wanted the players to have a more personal connection with the Lich King ... so we started designing quests and instances in which we could show the Lich King to the players." Developers also designed the game so that "players can see the wrecks of the Alliance ships that Arthas set ablaze ... they can also find the altar upon which Arthas first discovered Frostmourne ... We deliberately built these aspects into Wrath of the Lich King to help remind players who Arthas is and where he came from, which we hope makes his character that much more vivid in players' minds."
