Hey, listen, I gots some cool, dark stuff for you today. Go ahead, spray yourself with some lavender water, if you feel the need for protection. Keep the sage-burning to a minimum, please, it makes me nauseous. I said, "please", okay?!
Wanna meet some of my buddies? These are the ones you really don't want to meet in a dark graveyard. Some might do your bidding...for a price. Others you may not want to reckon with at all, unless you are feeling dark and nasty. I pass this information along to you as a, let's call it, public service, hahaha. Do with it what you will because after all, it ain't no nevermind to me.
Let's see, here's a good one to start with, the name says it all:
Buggar: These shapeshifting types never leave the astral world. Too bad, unless you travel there regular-like. They are very dangerous to humans and they really won't help you in your magick. Some people call them the Boogey Man. I wouldn't call them if I were you.
If you like to visit Faeryland, make sure these next guys don't follow you home:
Kolbalds: These dwarvish faeries like to make themselves at home and expect you to make your house available to them. They probably won't do work, mainly because they will sit around all day and night with their pipes. Funny thing is, they don't smoke those pipes. In fact, they hate smoke. If they think you have done them wrong, they will start tearing the place up, throwing stuff. They might help you set up protection spells for your house, but don't count on too much help. These guys are totally untrustworthy. Smoke 'em out, if you want to be rid of 'em.
This next bunch, man, these are bad:
Spriggans: If you are walking along, in the mountains say, be watchful of sharp rocks. Spriggins can look like rocks when they are on the ground. They can control wind and can puff themselves up into huge shapes. They are always in a bad mood, always looking for ways to make life miserable for humans. Maybe you don't want to deal with spriggans.
Here's another batch of baddies to watch out for:
Goblins and Hobgoblins: Malicious! Oh what a delicious word. You might want to steer clear of these guys, and definitely do not invite them to your house or yard. Some stories say that goblins didn't used to be so mean, but they hung around with bad human types and learned their evil ways from these undesirables. Some goblins are kinda runty, but some others learned to shapeshift to bigger sizes. They are ugly suckers, just plain evil-looking. They like to live in dead trees, messed up, run-down buildings, any place dark and musty and dank, you know, my kind of place. Watch out at night, because that is when they like to be the most nuisance.
Listen, I gotta go. All this talk of mischief and mayhem has put me in the mood for some bad tricks of my own. I will be back soon. That's a threat, not just a promise!! Remember! Nix on letting the Wiccan know that I have been tapping at the keyboard again. Catch ya, later!!!
