Oath of the Purging Flame

With the fall of the gods and their respective orders those looking for a cause to devote themselves to were found lacking. However the unending battle of the abyss divers and their zealous conviction to end the horrors of the pit once and for all welcomed all wanting purpose, thus the Order of the Scorched Earth was born. Serving as travelling knights those of the Order are the only ones within the abyss divers to never descend the pits fathomless depths; instead they travel the world looking for the earliest signs of abyssal corruption and bring their cleansing flames upon them. Kingdoms answer to the beck and call of the Order out of fear of attracting their burning gaze and the scrutiny that entails. Entire townships can be brought down by their purging flames if they believe the first seeds of the abyss has taken root and local militia must always answer their call to fight off gate lords and seal their vents from the pit. The ideals of the Order are that only from destruction can creation begin and, much like the former god of purity, sacrifice is necessary to improve the world, though the exact definition of corruption is not detailed within any of their sacred texts, instead being left to their knights discretion.
