"I'm your soul, your Shadow, YOUR FINAL TEST YOU MUST PASS SHADOWTHIEF!" said a being the same age and height of yourself. "you cannot hope to kill me as i am you, you were my host and i was your soul, you lose your soul and you die... common factor of life! I'll know all your attacks and how to beat them to kill you! TO BE FREE IF YOU TRY AND KILL ME!"

The Shadow is a type of soul for a member in the Shadowthief Clan. Being a member of the Shadowthief Clan is hardly a sacrifice, hardly even anything to have a burden upon yourself since you can control darkness and shadow!
