During the Great Conflict tremendous battles were fought in both the High Heavens and the Burning Hells. Both sides often carried the conflict deep within the realms of their enemies. During one epic battle into the very heart of Mephisto's fiery lair, a group of brave Seraphim warriors fronted an assault against the Lord of Hatred himself. One of these angelic soldiers made a bold attack and struck a fierce blow that caused the foul blood of Mephisto to rain upon the ground. Each drop that fell seared through the crust of Hell itself and formed powerful demons shaped from molten rock. These demons quickly rose to the aid of their master, and drove back the forces of Light by striking them with thrown masses of lava that seared both flesh and bone with the intensity of the Burning Hells. The losses dealt by these Magma Demons were tremendous.
