This is strangely similar in parts to my long work-in-progress fanfic of Arturia's life and I also got some new ideas for it as well!

Doesn’t this scence happens in Nasuverse already?
iirc Merlin used his hero creation skill to make her lower region to a man, so she
can have a heir, just didnt expect this was the beginning of the fall of Camelot tho.
