Given that Discord has the ability to make anypony believe that a small cloud is a city, or that a boulder is a diamond, why not make one believe they're living in a world of Chaos?

Since Discord's life hangs by a thread in the real world, he's left his beloved chaos in the back of his mind. When Nite Watch comes to him wanting to experience it herself, she uses it as a place to get away. Using the ability to go in her mind with the help of her draconic friend, she would occasionally see the world that she would have loved to live her entire life.

But after a year of her disappearance, she found the ability to return to his chaotic world. only this time, Nite Watch had a reason to get away.
