The Wrathful Flame is an Orcish religious order based in Wrothgar. Every ten years they light Malacath's pyre in ruins of the first incarnation of Orsinium. Legends says that for one thousand years they have honored the four clans who founded Orsinium and scorned those who caused its fall.
The order seeks to show Malacath that they will not repeat the mistakes of the past. They bind Malacath's anger to the failures of the Orcs and strive to remember what led to their doom. According to Malacath, rekindling the pyre every generation fuels vengeance in the hearts of his followers.
