The Citadel of Chaos

The sorcerer stands back from the table and laughs.
'Now I have you, peasant!' he gloats.
Cautiously, you step out from beneath the table.
That is, you try to step out.
But you cannot reach out further than the table's edge.
He has created invisible walls which now trap you underneath!
Try as you might, you cannot break through his barriers.
You are now his prisoner.

You have failed in your mission...

Start again from the beginning.
