Betrayed (Completed)

Disclaimer: I do not own Pokemon, I only own the region I created, my OC and AU.

This was not what Ash Ketchum expected to come back to after his journey in Kalos. Betrayal. Only Aeria, his first true friend and his closest stayed by his side and left with him, disappearing for ten years. When they suddenly receive an invitation to a tournament, what decisions will they make, and how will this change their lives?

And will Aeria's dark past resurface again, after 17 years? Will she finally understand the truth of her sister's betrayal? And will she finally get the revenge she has long sought after?

A/N: This is not a shipping story, and even though there is a Paul x OC and Ash x OC involved, it isn't the main focus of the story.
