SPOILER
Actually I read a spoiler that the Father indeed sought after the mage AFTER he realized that his Dukedom came down and he was basically dragged into ruins and he regretted executing Keira but it's kinda hard to feel remorseful for him when he only felt bad after he's power went to dust. According to the mage Keira remembered her past cuz the magic was use to turn back her time so she remembers (the mage knows he used the magic to turn back time but does not remember why) idk about why the duke got his memories but I want him to suffer
Maybe he gets the memories after her death it’s not like she can recall what happened after her head gets chopped off so maybe the duke and the mage split the past in half she gets what happened before she died and he gets what happens after the execution
ohhh. now i wanna see it drawn.
what if the duke is the one who made a contract with that mage to regress back in time but this time he wished for kiera to have her memories to be able to stand a chance against that demoness
