I might have some clue. During the World War II day I had to kill a few Nazis. I don't know what battle it was, but... They were my first kills that were 100% human and not, uh, hybrids of...yeah, let's just say they were my first kills that were entirely human.
That's another thing you should know. There are some nonhuman entities here. Vampires, werewolves, that sort of thing. I've heard there are some aliens, too. They're not inherently evil or anything.
No long lines and you get there in an instant. It's pretty much teleportation.
