The 42nd Supreme Being (Overlord fan fiction)

Before I start with the warnings, do NOT let the title mislead you. I am technically supreme being number 0. That will be explained later in my backstory.
Oh sorry! My name is Nagisa Snaka (I know, odd name, my creator should have picked a better one, yes, I am looking at you Puppet Killer).
Now, before the story starts there are a couple of warnings.
The images seen or the original characters of Overlord, my creator does not own.
Some events may be altered or be removed for the story while new events may appear. The writer apologizes if you are not satisfied with the changes done to the Overlord story.
The actually story of Overlord I do not own and I highly recommend you check the Overlord series if you haven't.
With those out of the way, time for the prologue! My backstory!
