Menoth's Fury is a substance produced from refining oil found beneath the cracked soil of the Bloodstone Marches. Unrefined, the oil is used to fuel the forges and temple-hearths of the Protectorate. However, Hierarch Turgis discovered that, refined, the oil could be used as a lethal weapon. Indeed, the more refined the oil is, the more dangerous and flammable it becomes.
Nowadays, the refined oil is used as fuel for the Flameguards flame spears and purifiers, the Repenters' flame thrower, the Crusaders' inferno mace, the Vanquishers' flame belcher, the Castigators' flame fists, and the Reclaimer orders' incinerator torches.
