My shalafi, which is an elven word meaning roughly teacher, sought to become a true god. Immortal, in the sense that he would live forever and sustained by his magic alone.
It can be, if you prefer. Otherwise, I say a few strange sounding words and you fall asleep. I would just need to gather some ingredients for a potion.
