Re: Explaining everything...
"Well, there are more supernaturals around than most people are ever aware of," Jeannie responded, "But no, that's mostly because Mysteria is a nexus. A place where several ley-lines - which are energy lines that run across the face of the earth - converge. supernaturals are just attracted here, whether they're aware of the fact or not. it's sort of like... a homing beacon. Additionally, there's a fairy mound close by."
There was also the hellgate, but Jeannie wasn't going to tell about that.
"Yeah, get this, Eden," Tyson put in, "Fairies are real too. And it turns out most of 'em aren't little teensy tiny flying things. They look pretty much just like everyone else."
