Legion of the serpent

Bring forth the commencing days
An infernal Saurian nemesis appears
The keepers of Earth
Inferior minions of draconian descent
Enforcing the rules of the ancient covenant

Blazing orbs of the Sun
Beating on a helpless Earth
The serpentine order shall no longer hide
The dimensional door brings the Gods to their side

Warm blooded sacrifice to appease the thirst of the creatures who've hidden so long
A servant of the omni-dimensional
tall and strange bloodthirsty sentinals
Sent to possess the hybrid creation
Dimensional domination

Keepers of the doorway between worlds
Patrons of destruction
Planters of ignorance
Breeders of malevolence
Sorcerers of possession
