The first war

Before Oros took notice of the little ball floating in the material plane, it was awash with fire and misery. Denizens from other planes came here to battle, hunt or simply cause misery on the few creatures able to survive here. Such chaos saddened the diety and he called upon his kin to direct their power and protection over the world. He began by pushing the blazing heath to the underside of the world so that mortals might flourish. Next he implored them to take the realm for their own. Emboldened and empowered by the divine, humans, elves, orcs and dwarves stepped up and banished the invading elementals and soulless denizens from their continent henceforth known as Stralis. Even after the fierce war there remained many extra planar abominations roaming free in the far away corners of the world. The gods decreed no mortal under their gaze would break the planar veil lest the chaos of before would return. Oros himself laid down laws to live by and left the mortals to live and learn under these tennants. The chosen and devoted amongst them would watch over the piousness of their flocks and protect them from the extraplanar treath.
