Black Angel

Rule number one: if you can't control it, [..] justice

An ancient relic, of sorts

A fossil to be more precise

An angel, but not just any ordinary angel

They found the first angel

Lucifer, the black angel

They found the exact spot where he fell to Earth

After he was cast from Heaven

It's this one you have to worry about

Evil flows through her veins

She'll turn on you when you'll least expect it

A manuscript that foretells the period when Hell will reign on Earth

Evil come to you in many forms, the face of an angel

For I, the bringer of death

Rule number one: if you can't control it, [..] justice
