Terenas: Ah, my son...

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.

*Arthas approaches Terenas and draws his sword*

Terenas: What is this? What are you doing, my son?

Arthas: Succeeding you, Father.

*Arthas impales Terenas; Terenas lets out a death rattle and his crown falls to the floor, broken and blood-stained.*

Arthas: This kingdom shall fall, and from the ashes shall arise a new order that will shake the very foundations of the world!
