The Blade of the Fallen Prince

  • The Call of the North – The Lich King awaits your return to the citadel.
  • The Gates Are Open – Enter Icecrown Citadel.
  • Seek the Fragments – Collect Fragments within Icecrown Citadel.
  • Travel to the Frozen Throne – Use the Scourge Teleporter within the Spire.
  • Power Overwhelming – Reforge the fragments and form your weapon.
  • The Purge – Purge the blades of the malevolent souls within.
  • The Hungering Cold – The Blades are purged of the corruption. Claim them as your own.
  • Death’s March – Obtain the Lich King’s Blessing.

That last one though? Is it Bolvar or is it the Lich King?

Bolvar IS The Lich King

I mean in the sense that, The Lich King was all “Watch now as I raise them from the dead to
become masters of the Scourge. They will shroud this world in chaos and
destruction. Azeroth’s fall will come at their hands – and you will be
the first to die.“

And then 2 minutes later Arthas was all “Father? Is it… over?“

The same thing might apply here.
