Well its not a easy quest at all (only on Taurus i see maybe 1 or 2 at most people with her) but its only been out a few days so idk
but the fight (start of the quest) is in the forest that you use to get to Domremy (go to Egypt go into forest and take the bottom left exit with Sea Vehicle) go up past Rome and enter the forest past that when u get there go north near the portal you fight 8 or so knights vs you 2 other people (hopefully) and Joan thats all i personally know right now so at least its good enough to get a start
