Can one soul prevent Oblivion? Maybe with a little help from her friends
Maebh had discovered early on that of all the things she had to deal with, sometimes using her middle name was easier than explaining why "Maebh" was a trick name. So she was Mae to her close friends, Hellenna professionally (Siobhan, again...arguments).
So, when she died, she thought there would be a feather, her heart, points would be awarded for not dicking people around with her name, and maybe time for an "Oh bugger," if she was eaten.
Instead, she awoke in a place that could not be, surrounded by nine people, weapons drawn. And they were all squabbling over who could claim her soul! Each chased off the other, until a voice thundered "She's MINE!"
And that's when things got a bit complicated. Each of the nine Reapers' gods appeared. Eight of which she had venerated in one way or another. And one she had to be introduced to. The ninth, sputtering at the indignity, demanded, that to make the Game fair, she is partnered with another like her.
So...the Game was proposed. Souls as rare and open as hers were hard to find. Each reaper's next 20 claims would be weighed, measured and held. The pantheon with the most got the prize...Except, the reapers could go anywhere in time to find them, so there was no time limit. Probably a good thing.
Mae's job? To ensure they were taking people at their time, not before and that they were not interfering with the people they collected beforehand. Not easy when she had 10 people to watch, including her opposite.
Oh, and if the God she didn't believe in won, her existence - the Universe - will be completely obliterated. Heaven hath no fury like a diety unacknowledged...
