Black vengeance of the ancient hordes

From archaic temple ruins
Hidden out of space and time
The forgotten aether of primordial spawn
Formed in dark matter
Unleashed in the energy of cosmic black holes
Reaching into infinity through the silence of black dwarven stars.

Awakens a cold malevolent force
Shapeless formed creatures come forth from the shadows
Grotesquely horrid abominations from beyond the outer spheres.

Twisted malign horrors breed death and destruction
Returning the world to the depths of voidal abyss
Hate filled black skies rage
Bringing furious storms
Charged electrical currents scorch and burn the earth
Lords of chaos take to their wings
Raising hordes of ancient creation
By broken seal through open gate
Ascension from the lower realms.
