Thirst for revenge - S1.E9

Azta is chained in the basement, and there is no point in promising that she will save Mia if she is released. Only Azalie knows how, and she will only wake Mia when Azta has sacrificed a soul. Freya fools Azalie and finds something in the local books that helps her understand why Azta gets burned by invisible flames and what will happen if the flames are not stopped.
