The Citadel of Chaos

The suits of armour are a variety of shapes and sizes
and you shiver to think of the strange creatures they must have been made for;
perhaps you may yet come across some of them.
As you examine one particularly grand suit,
its hand suddenly rises and whacks you across the face!
You stagger back, spitting blood.
But the armour makes no further move,
and you decide it may be prudent to continue upstairs,

either up the left-hand staircase,

or up the right-hand staircase.
