Well... I did mention talking more about my own aus instead of hoarding them a while ago so might as well start with the one that my current icon was made for oh so long ago
They call it Newhaunt
It was ages ago when and out pour of monsters came to the surface, all coming from Ebbot Island and its mountain. monsters spread out all over the world. Politics happened quickly and quietly, the public fascinated with a new species, and governments interested in the magic. It was a fairly easy transition, or at least that's how people talk about it now.
Years ago half of Ebott island disappeared under the water after being wracked with earthquakes.
News reports say there were no survivors, human or monster. They say there's a type of magic radiation emanating from it, unpredictably dangerous. The entire surrounding what's left of the island has been cordoned from the public, nothing in and nothing out.
But where there's a Will there's a way. Anyone tangled up in urban exploring and conspiracy circles calls the magic radiation claims a crock of bullshit. Groups sneak in, most come back.
Those who come back swear the place is haunted. They never have evidence, they never stay long enough to get any, and are always written off as proof of the magic radiation, their loved ones waiting for them to start wasting away. When someone does go missing, no one seems to think on it long.
The most common types to set out for this place are ghost hunters and conspiracy theorists. It's not unusual for relatives of the people who once lived there to go looking for answers either. There's been talk of scouts for companies wanting to find some resources there, and there is of course, the occasional stow away.
