The Citadel of Chaos

She watches in astonishment as an exact duplicate of herself appears between the two of you.
She backs off a little and you instruct your creation to attack.
But as they get close to one another, a strange thing happens.
They seem unable to get close to one another,
like two spinning tops, and keep bouncing apart.
But your own copy has at least forced the creature back some distance away from you,
allowing you to run to the Citadel's main entrance.

Press on forwards.
