Volume 12 - Bonus Sidestory
Time flowed onward. Princess Mia was captured, thrown into the dungeon, and executed at the guillotine. Under the rule of the revolutionary army and Sunkland forces, peace and safety gradually returned to Tearmoon. At the same time, Petra's body similarly marched toward recovery. One day, when she could get out of bed and walk without issue, the nun from back then approached her.
The following paragraphs seem to describe the day of Mia's execution, so the past tense seems to be inappropriate for this.

Also, for a blast in the past
Volume 1 - Chapter 4
"Your Highness, I pray that the gods will smile upon you. May you go with their blessing" >> We now know that Tearmoon (and the continent in general) practices monotheism. This should probably be God or The Holy Deity. I check the web novel and Ann doesn't use the explicit plural 神々, so with the context of the later novels, Ann was very likely just invoking one God.
