Cinematic: Arthas’ Betrayal | Warcraft III: Reforged
King Terenas: Ah, my son. I knew you’d be victorious…
Arthas: You no longer need to sacrifice for your people. You no longer need to bear the weight of your crown. I’ve taken care of everything.
King Terenas: What is this? What are you doing my son?
Arthas: Succeeding you, Father…
(Arthas impales his father’s chest, through and through, with the Frostmourne runeblade).
(The bloodied crown rolls down the stairs and breaks)
Arthas: This kingdom shall fall, and from the ashes shall arise a new order that will shake the very foundations of the world.
