Crossing Over

It's well known that every soul when finished with their mortal life crosses over, so why didn't I?

My name is Veren, and I am the only ghost in the history of the world to not cross over. How do I know? I was there even before time was time, before existence even existed.

I suppose everything comes with a price, though I didn't expect my immortality to come with this price. I must protect each and every child at night from the demons that haunt them, and battle them all.

Yet nobody else ever has taken my job for me, I presume it's because of the dangers.

Of course, I can't blame them, who would voluntarily fight demons much, much powerful than you each night. 

I work tirelessly almost 24/7 to help each child in the world. I can't protect those who consider themselves "adults" as it is common sense that they 'don't believe' in "monsters". Even if they begin to doubt it I cannot help them any longer.

The way my job works is for each kid that goes to sleep, I multiply twice. Every time I multiply I get slightly weaker though, so for each kid's demon, I defeat my 'clones' gain their strength in battle. 

If I am defeated by a demon it is only that portion of me that loses strength as each 'clone' is in their own battle and only their own enemy can harm them. Confusing, I know.
