The Age of Fire
Led by Gwyn, the Lords of Soul and their armies led a rebellion against the dragons. Seath the Scaleless, a conniving dragon, betrayed the secrets of his own kind in the hopes of acquiring the immortal power of the Primordial Crystal, held captive by the dragons.
Armed with the knowledge of the dragons’ weakness, Gywn and his men hurled lightning at the dragons, thus ridding them of their scales, rendering them mortal. The Witch of Izalith, along with her Daughters of Chaos, cast a series of firestorms that burned through the dragons’ homes – the arch-trees. Nito, in-turn, unleashed a miasma of death and disease on the dragons until their bodies crumbled away.
With the land rid of Dragons, the Lords of Soul took dominion over the land now known as Lordran, from atop their royal throne at Anor Londo. During this age of prosperity, humanity thrived and civilization grew for several years. But like all things, the Age of Fire soon came to an end.
