Is an imperial affliction a real book?

"An Imperial Affliction" is not a real book. It's likely a phrase you've encountered in a fictional context or perhaps a title you've invented.

If you could provide more context, I might be able to help you further. For example:

* Where did you hear this phrase?

* What is the overall context of the phrase?

* Is it related to a specific story, game, or movie?

With more information, I might be able to give you a better answer.
