The thing is, MMU has more mystical creatures than just the ghosts in the library and the fifth floor of FOB. There are a couple more as well that we didn’t know existed. Things might get a little creepy over here, because who knows, you might just be living with one of them. Just saying!
Sometimes and only sometimes, they would crave for more (surprisingly, they have lots of self-control), so they find innocent and lonely mortals, lure them to a dark valley, drink their blood and erase their memory by compelling them to forget everything that happened. Now you know why you’ve never seen any of them!
They are the ones that disappears the whole day and appears the next morning and pretends like nothing happen. So, if your friend says he or she went to bear hill yesterday, he is secretly a werewolf. Beware! Werewolves howl can be heard often during a full moon. Just listen.
Well, you might be a wizard, Nah, Just kidding. However, wizard are not allowed to expose magic, so usually you won’t notice them, they are just there. By the way, you don’t want to offend a wizard, as you might wake up the next morning with a large zit or a stomach ache. Just saying.
