Frostheart is a somewhat obscure legend of the Northrealm. Based on the rare interactions and study of the tribes of the Frostfangs, (Coldars, Sryllans, and Helgoblyns), it is either a place, artefact, or some form of deity located deep inside the glacial caves of the frozen peaks.
Owing to the difficulty of the terrain, to say nothing of the very hostile natives, efforts to locate Frostheart have proven completely unsuccessful. The main argument for its actual existence is the obvious similarities between Coldars and Brobdangeon, and the Helgoblyns seeming relation to other Goblyn populations. Speculation that both are their apparent cousin-races transformed by Frostheart leads the anecdotal arguments for its existence.
