In retaliation for his brutal magic of annihilation...
The Demons descended upon Asmodeus's force like a tide of darkness.
Their bodies were thick, clad in black scales, hands deformed and shedding sharp, blade-like claws smeared in blood and black tar. A viscous liquid that dripped down the ground.
"Charge!"
Asmodeus ordered the Demon Knights to rush forward and stop the swarming demons, who looked like nothing but locusts to his eyes.
Erika led her group into battle, galloping on their demonic steeds with low, drumming sounds as they struck at the earth.
The Demon Knights and their charge tore through the frontal swarms, bodies falling apart at their blades' touch, causing many of the lesser Demons to explode in gory bursts.
A sense of victory and superiority took seed in their chests as they became confident.
Alas, this might have been the reason...
