So Tangled
If Gryffindor's Illusion Test is to describe the entire Middle Ages, it will be like opening a grand new map. It will take dozens of chapters to write, which will seriously slow down the rhythm of the main plot.
(To be honest, the main plot of this volume is already slow enough, I can't imagine how long it will take to open a new map)
Another option is to let the protagonist concentrate on solving clues, completing the test, exploring the new world, etc., and leave it to the side story.
What do you think?
Does anyone really want to see the stories of Merlin, Morgan, King Arthur, Morrigan, Cleona, and Knight Cadogan?
PS: Does Qidian have any HP fan fiction about the Middle Ages? I want to see it.
