If you care to glance out of the corridor windows on your way to the Transfiguration classroom on this mid-October morning, you’ll notice that the sky is typically dreary for this kind of year -- grey and overcast. Don’t let that get you down in the dumps though, Professor Darlington has quite the lesson planned.

Upon entering the classroom, you’ll be surprised (or not, this is Hogwarts after all) to find that you haven’t walked into a classroom at all. The classroom has been charmed into what appears to be a large, open clearing outside on the grounds. It’s still morning, but in here the sky is a clear pale blue and there isn’t a cloud in sight.

The only thing out of the ordinary you’ll see, is the portable blackboard in the middle of the clearing and this is where Professor Darlington is standing and waiting, arms crossed and expression neutral.

Well, don’t dilly daddle! Come on in and find a spot to stand.
