The Cursed Stairwell

The Cursed Stairwell refers to a stairwell located within the Castle of Kung in Kung which has been cursed to force anyone it deems 'unworthy' to remain trapped within the stairwell forever, either climbing or descending it without ever reaching a top or a bottom until eventually they die.

The Cursed Stairwell is used by the nation of Kung to test the ability of a potential future King of Kung before appointing them to the throne. Should they enter The Cursed Stairwell and find their way to return, their worthiness is proven.
