Shackled

Artemis was once the goddess of the hunt, glorious and free. Wild. But one day, she makes a mistake. And she is punished for it in the worst possible way.
Now, she is bound, imprisoned and extraordinarily, exceedingly, mortal. She needs to repent for her mistakes. But imprisoned in a cell, deep underground, with no weapons and no hope, Artemis is sure she will remain as a mortal until her time runs out, and she withers away in a cell. Until one day, a girl opens her door.
