Given that Old Gods can be shaped by human belief -- and that human belief can make them more powerful -- does anyone else sort of wonder if there isn't some Old God out there who might not have actually latched on to the Santa Claus legend as a source of power?

And this being might have been an imposter at first, sure. But the belief of hundreds of millions (billions?) of children worldwide would start working on him very quickly, and before you know it, his memories and personality are changing...

Soon enough, you wind up with a new, vastly powerful Old God living at Netzach's North Pole, presiding over a toyshop full of very tiny Fey.

And this Old God does not take kindly to Leviathan trying to wipe out all the good little boys and girls of the world...
