The Citadel of Chaos

The staircase creaks as your foot falls on it.
You try to ascend as quietly as possible, but the old timbers groan under your weight.
Suddenly one of the stairs clicks as if to trigger a switch of some kind.
To your surprise, all of the stairs flick downwards!
You are now standing on a smooth, steep slope!
Try as you might, you cannot keep your balance
and you fall down the slope, tumbling head-over-heels.
If you wish to use a Levitation Spell, you may fly up and out of danger,

to land on the balcony above
