Constant vigilance is always advised, and a relatively redeeming quality in the face of unrelenting curiosity and the impulse to step into the light. Those who venture as far as the first passage will find nothing dangerous or frightening waiting for them, though perhaps the lack of any action will only contribute to the building suspense.

Progressing on through the next doorway, which once led to a large chamber...

... there seems to be nothing dangerous in here either (fortunately for the more curious cats among you). But it is a strange sight nevertheless.

An outdoor scene lies ahead, oppressively hot beyond the threshold, and brightly lit with sunlight shining from the azure sky. The entrance stands where sand dunes transition into forest, and a body of water is visible, glittering in the distance. It's a huge outdoor environment, clearly not naturally occurring within the castle, nor within the country, but if you were to explore further afield you would find that this chamber is still exactly that, extended and rigorously enchanted, existing entirely within the boundaries of the school.

One thing is for certain: whatever was in here, it's not here anymore.
