Hello! Just a quick introduction to the world this is set in before you start reading the story. I'm laying down a framework to define the monster heaven of Supernatural further for this fic and any other ones I decide to do after. I think Purgatory is a potentially very interesting place and there is infinite room for storytelling about it. But we don't know that much about Purgatory at all, we really only scratched the surface. So, here is my take on it.
Purgatory
Death
If you experience death in Purgatory, you are at true rest until your soul regenerates to resume the hunt once again. Those who survive longer take longer to come back, some of the most ancient beasts in Purgatory could be all but banished permanently if they were taken down. This is one of the reasons why there aren't actually millions of monsters running around in Purgatory all the time. There is a sustainable amount of predators and when there are too many Purgatory itself puts them together to force conflict and death.
Terrain
There are all different types of terrain in Purgatory. Mountains, deserts, swamps, forests, it's all there. Monsters gravitate towards their preferred hunting grounds and often stay there until killed or driven off by stronger ones or one of the many volatile groups that form.
Time
Purgatory time runs parallel to Earth time, a second is a second and a year is a year. Day and night cycles are a completely different animal.
Day & Night
There is no sun in the sky, just a dull glow through endless clouds that casts the world of Purgatory into a grim setting. There is a day and there is a night, but they can last weeks at a time. There is always a strong upsurge in meeting other monsters and violent encounters during one of the long nights. It is Purgatorys way of lowering the population, sending more souls into regenerative states to maintain a balance. When the population rises too high, darkness closes in and it won't lift until enough death has been dealt.
Weather
There is no extreme weather in Purgatory; no rain, biting cold or baking heat. The only active weather to speak of is the fog that rolls around seemingly at random. It is like a safety blanket, injured or doggedly pursued monsters can hide in it and stand a chance of losing their hunters.
