Sylvanas' Farewell is an interlude in the undead campaign Legacy of the Damned.
Script
Banshee - This is the place, sisters. We'll rest here, great king.
King Arthas - Why here? We've got to find Kel'Thuzad before we--Aarrghh!
The Lich King - You have been deceived! Come to my side at once! Obey!
Arthas' minions die.
King Arthas - What is happening here?
Arthas is struck by an arrow.
King Arthas - Sylvanas!
Sylvanas Windrunner - You walked right into this one, Arthas. It's time to even the scales.
King Arthas - Traitor! What have you done to me?
Sylvanas Windrunner - It's a special poisoned arrow I made just for you. The paralysis you're experiencing now is but a fraction of the agony you've caused me.
King Arthas - Finish me, then.
Sylvanas Windrunner - A quick death... like the one you gave me? No. You're going to suffer as I did. Thanks to my arrow, you can't even run. Give my regards to hell, you son of a bitch.
Kel'Thuzad arrives with a group of skeletal magi.
Kel'Thuzad - Back, you mindless ones! You shall not fall today, my king.
Kel'Thuzad and his magi destroy Sylvanas' banshees.
Sylvanas Windrunner - This isn't over, Arthas! I'll never stop hunting you!
Kel'Thuzad leads Arthas to the shore.
Kel'Thuzad - The effects of her arrow will wear off in time. All the preparations for your journey to Northrend have been made.
King Arthas - You have been a loyal friend, Kel'Thuzad. I don't know what the future holds, or if I'll even return, but I want you to watch over this land. See to it that my legacy endures.
Kel'Thuzad - I shall, King Arthas, I shall.
