BAD THINGS TO COME ACROSS WHEN VISITING A MAGICAL WORLD

1. The sound of a dragon or other monster landing behind you.  You hear a strange noise, you turn and there it is...  so either run, use a spell to destroy the thing or hope St. George turns up.
   
2. The annual convention of the Wicked Witch Society.  They tend not to like being interrupted.  They also have so many ways of showing their disapproval at that interruption, all of which will be fatal.
   
3. A society that likes human sacrifices - and then you show up.
   
4. A quest that needs one more to make up the numbers - guess who that muggins will be.
   
5. A magical ring with strange inscriptions on it.  Leave it alone if you value your life!
   
6. A magic lamp or artefact in general.   There is always a price to pay with these things.  At best you'll get a genie who tries to be too helpful (they're usually in a hurry to get rid of the old three wishes obligations as that sets them free from the curse that shoved them in the magical artefact in the first place).  At worse, the genie has been waiting for some muggins to take their place in the magical artefact and then you show up!
   
7. A map promising to show you the way to immense riches.  It is unlikely to be the only copy and you will have no idea who else is hunting this treasure down.  If you like a long healthy life, it is best you leave these maps alone.
   
8. Food or drink with labels encouraging you to eat or drink them.  Well what else were you going to do with them?  Also I'd be very wary of food and drink being left out like that.  There is a word for this kind of thing.  It's "bait".
   
9. A helpful guide who volunteers to show you around the magical world.  They've almost certainly got their own agenda (and maybe they are on commission to lead suitable victims to those requiring such things - wicked witch, wizard etc).  Ask yourself just why would they want to help someone who has just turned up in their world.  What are they getting out of it?
   
10. A sword in a stone.  It isn't for you, honestly.  Leave alone.
