This story is a sequel to The Emptiness of High Valour
Empty Valour was made a prisoner and then a slave when the changelings invaded Equestria. Having endured torture and abuse, she meekly submitted to her owner until she was brought back to Canterlot as a part of her mistress' household. The alterations to society brought by the changelings force her to confront her worth as a unicorn who was robbed of everything she held dear, while her fellow citizens who remain free advance their own power, wealth and status.
