Echoes of Oblivion

The illegitimate princess Ellesia had spent her life in the palace mainly being ignored by her family, and she learned to be okay with it. But a coup was staged, the kingdom usurped, and the royal family executed. Now in hiding, as the last remaining member of her family, she has to learn how to live life outside the castle, gather funds to support herself, and put together forces to reclaim her right to the throne.

This is the first story I've ever done like this, the idea came to me after making an au for a manhwa I read on Webtoon, and I've been brainstorming ever since!
