Enhancing the Dead Undeath

Sepulchral supremacy
Beginning with a corpse and ending with machine
Augmenting through butchery
Cities of life, now cities of the dead
Bolster the undead army

Tissue from the brain analyzed
Tissue from their brain prioritized
Tissue from the brain was dead but is now alive

I give them powers from below

Necrobionics, attaching metal to flesh
For war I am
Enhancing the dead
Will walk the earth
Outnumbering life
Conquering humanity

Scenes of slaughter
Milling their skin for additional enforcements
Innumerable scores of dead
Take the fight beyond this earthly realm

Necrobionics, attaching metal to flesh
For war I am
Enhancing the dead
Will walk the earth
Outnumbering life
Conquering humanity
