Frostmourne Cavern



Frostmourne Cavern is a cave located at the base of the Icecrown Glacier where the dark runeblade Frostmourne lay. Its entrance was protected by a revenant known as the Guardian, before it was slain by Arthas Menethil, who then claimed the blade. The cavern was given its name by the Scarlet Onslaught.

Players can see here a flashback of the last interactions between Arthas and Muradin Bronzebeard as originally seen in Warcraft III, with a surprise ending showing Muradin's survival. Next to Frostmourne's altar also lies Arthas' former hammer, Light's Vengeance, as well as Muradin's weapons, frozen in the snow. The cave is also teeming with saronite.
