We don't know why they copypasted the Arthas book summary for the auditions
"His evil is legend. Lord of the undead Scourge, wielder of the runeblade Frostmourne, and enemy of the free peoples of Azeroth. The Lich King is an entity of incalculable power and unparalleled malice - his icy soul utterly consumed by his plans to destroy all life on the World of Warcraft. But it was not always so. Long before his soul was fused with that of the orc shaman Ner'zhul, the Lich King was Arthas Menethil, crown prince of Lordaeron and faithful paladin of the Silver Hand. When a plague of undeath threatened all that he loved, Arthas was driven to pursue an ill-fated quest for a runeblade powerful enough to save his homeland. Yet the object of his search would exact a heavy price from its new master, beginning a horrifying descent into damnation. Arthas's path would lead him through the arctic northern wastes toward the Frozen Throne, where he would face, at long last, the darkest of destinies."
