From the introduction:
Oh gosh, sorry! I didn't see you there - but, hi! I'm Valeks, and I can tell you're kind of new here but don't worry, I'm here to help. Welcome to the world of Goodbye Strangers. Why do I refer to it like that? Well…you'll find out.
So, to give you a sort of basic rundown of Goodbye Strangers - in this world, there are these things called Strangers. They're weird, and most of them are dangerous or have negative effects - both for normal people who can't perceive them (we call them standards!) and for those who can see them, which we call sensitives. Sensitives come in three types - Dissemblers, Laminates, and Projectors, but there are also Psychics, Blanks, and Mediums! There are also Empties, but uhh, you don't want to be one of those. Then you have what unifies all the different sensitives (except Empties) which is a Thoughtform, and from there you have stuff like Ghosts or weird things like Nurenforms and Meoms and…
Whoops, I'm kinda getting off track here. Anyways! What you need to understand is that there's loads and loads and loads of stuff here, and I'm not really sure I can get through all of it…but I'll try my best!
