Blades of the Fallen Prince (Icecrown Citadel)

SS Icecrown Citadel

The Blades of the Fallen Prince subzone is a spiritual realm inside the Blades of the Fallen Prince where a player is transferred into to cleanse the artifact weapon formed from the shards of Frostmourne from powerful spirits Echo of Arthas Menethil and Echo of Ner'zhul that remain within the blades.

It is identical to the spiritual realm inside of Frostmourne.
