Abhorrent rite of unbinding

Life is too short for me
To learn all I must
Knowledge and mysteries
Books gathering dust

To hone my eldritch might
More lifetimes I must live
Escape mortality
The gods will not forgive

Deep in the darkest texts
I find the rites that I need
Unbinding soul from flesh
Requires that I bleed

Mutilation
Excarnation
Defilement
Condemnation

Open my veins
Into the golden well it drips
Inscribe forbidden words
Upon the parchment strips

Perform the ritual
Black magic will create
Precious phylactery
To keep my essence safe

From this day forward
I will never be more whole
Into this ebon box
I seal away my soul

Initiation
Incantation
Recitation
Invocate

The years wear on
The flesh has fallen off my my bones
My power grows
As I devour ancient tomes

A crown upon my skull
My eyes are empty pools
I drape my bones in silk
Replace my teeth with jewels

Enslaving mortal men
I feast upon their lives
My soul lives on
Until the end of days arrives

Coronation
Profanation
Conflagration
Ruination
