Schleich - Dementor

Pitch-black and silent, the Dementor floats in with his cape fluttering behind. He seems to be heading for Hogwarts. I wonder who he's got in mind there? You certainly don't want to bump into him at night - he is so creepy and very dangerous! He robs his enemies of their souls. Terrible! I wonder if he can be stopped with the right spell?
