The Great Battle of Darkness was a climactic battle waged against the hordes of the Great Old Ones by the Alaxaran pantheon and their mortal allies. It resulted in the breaking of the Cycle of Ruin and the vanquishing of the old gods.
Background
When the ninth and final Ruin unexpectedly began in 1 BA, the emergence of the old gods' hordes was a sudden shock to the nations of Addar, but an immediate resistance was raised by King Anharos of Aevinn, a pious man much favored by Alaxar and his court. Anharos assembled the most able fighters in the land and shared with them the powers of the Diamond of Purity, an artifact earlier gifted to him by the gods that granted profound strength against evil and undead foes. Dubbing them the Knights Adamant, Anharos led his warriors against the hordes and slaughtered vast numbers, the power of the diamond burning through the adversaries like fire.
Behind the ranks of evil beings rose the Great Old Ones themselves, malevolent deities who advanced across the face of Eamon toward Anharos and his alliance. The strongest and most vile was mighty Xor'urr who in form was like a massive thunderhead of ink-black vapor that instantly poisoned and killed any living thing it touched. With it came Gorlith the Shatterer, the mind-bending T'Zzanti, and other eldritch monstrosities. Anharos called upon the gods themselves for aid, and Alaxar and his fellow deities answered, girding themselves for battle, throwing open the portals to their elemental realms, and meeting the old gods in combat on the Plain of Sarkarm.
The Battle
The goddess Terza led the attack and engaged Xor'urr directly, lashing the battlefield with vast whips of solar fire tens of miles long, channeling the radiance of Alaxar himself into a blinding attack that shattered and melted the very landscape beneath the enemy. At the same time, the old gods sprang their own trap by forcing the god-herald Agamon, secretly infested by the T'Zzanti, to turn on his allies. Thousands of allied fighters fell to his sword, and the goddess Brynne badly injured, before he was mortally wounded and subdued by Weyren.
Enraged, Terza and Alaxar pressed their attack; the vast and nearly impenetrable shrouds of darkness protecting Xor'urr and his lieutenants were burned away, exposing the god's putrid core to the incinerating light of the sun and annihilating it from the material plane. The other Great Old Ones quickly fell or fled, and the remains of their monstrous legions scattered, hiding themselves deep under the ground or in the wilderness.
