This one is many things. It is what you get when you die and remember all the lives you've been through already. It is a speck of energy - the point of view to any creature it inhabits. It is their "soul".

It is also the Gatekeeper of the Fade. It took over the job so the previous gatekeeper could have their eternal rest. This ones' favorite life was a lying actress who died in her sleep of werewolf injuries. Because of the actress's influence this one likes to dress up for its new role. When other bits of energy start going numb from passing through too many lives then this one introduces them the other available options. It also keeps an eye out so that no-one who shouldn't would enter or leave The Fade.

This one knows how the world will end. It wishes it was not this soon.

Shame it can't do anything. Were this one to go to Earth by becoming a soul in yet another creature it would no-longer remember its purpose or its other lives - it could not interfere.

And surely it can't just go to Earth the way it is.

Someone would stop it if it tried.

Someone like...The Gatekeeper of the Fade?

...now hold on a moment!
