My Frostmourne can't be so cute

Twenty years after the opening of the Dark Portal, Prince Arthas of Lordaeron drew out the sword of Frostmourne, and the undead natural disaster swept across Azeroth;seven years later, the Tribunal of the Ashes captured the Icecrown Citadel, and Lord Tiri Overdin killed Arthas, ruined Frostmourne, and the battle ended.After getting Frostmourne, Arthas betrayed his kingdom, abandoned his people, and killed his father and teacher;if everything was over, would he make a different choice?An inconspicuous wave flashed in the long river of time, and the development of the story turned to a new tributary. The future ahead is a fog that the bronze dragon king Nozdormu can't see through;Thrall, Jaina, Garrosh Hellscream, in the face of turning time, how will all the people and events we know usher in unknown endings?
