Red water.

Red water, red water how do you bleed
you've been accused of murder, how do you plead?

My children within, I needed to feed
I took what was required, and the rest were freed
you'll never comprehend the complexities of this deed,
for I pre-existed the first mortal seed
I understand better, the immortal creed.

Red water, red water how do you bleed
you've been accused of murder, how do you plead?
