Honestly, I wish you would return to this. It's a pretty interesting concept, and like DivineBahamut said, its AU anyway, you can make some changes to canon to fit the crossover nature of the story. Most fanfics aren't 1:1 in terms of maintaining canon, especially in the mechanics of magic systems and the like, so take a few liberties if need be to make you story fun and people won't really complain.

Screwed something on the Fate side of things? You are debating if you have to rewrite or drop it? If by dropping you mean scrapping it, remember there is a third side to in coin that is the edge: you could just proceed as you have so far, modify the lore of both franchise if it better the story you want to write and justify it with a "Screw canon, this is fanfiction, dammit. It already is an AU, anyway". Any flamers that whine because you are altering main and/or background lore, just answer "All fanfics are AU already, so suck it and shut it".
It's not like people read fanfics to see something different from the canon source material. Oh wait, that's why people actually create and read fanfics. So if anyone complains and whines because you aren't following the lores letter by letter, ignore them.

As far as I am concerned, you had been doing a good- NO-, a superb job with this story, and I look forward to see where it goes.

this was nice and I loved it, those two are a great duo

Great chapter, Medea and Taylor finally talking was good as is the magic training going to eventually start is gonna be awesome.

Though its odd Taylor was that worried about the colored tips of her hair considering she could just say it was an incomplete dye job or something

interesting, i love the idea of Elf Princess Taylor, so is she like a demi servant?

I don't particularly like the whole "you might not return to the throne" thing mainly because i have read of it before and it was poorly done, Seems like it would be easier to just say someone (Taylor) was calling to Meda that would summon them as a Servant.

Otherwise great beginning chapter

I really kinda want to see where a story like this goes it’s a really cool idea

One thing you skipped over is how to use the language without activating the spell, while useless in modern day it seems like something Taylor would’ve asked about for curiosity’s sake

Just found this after reading Sisters Grimm. I hope this does eventually get picked back up, either as a rewrite or continuing as it currently is. It's an interesting take on a fate crossover. Having seen how Medea fights in Fate, if Taylor can get even half as accomplished then she'd be a force to be reckoned with. Medea's teleportation and laser spells alone would make her one of the top capes in the city, if not the country.

pls continue this great story

pls continue

cool story i like the ideal

I think the story is very good and even kinda cute so far.(and considering both Medea's and Taylor's history/allotment intheir respective series, I say their due it.)

So I say keep plowing on the way you have been and if you're worried about your fate lore concerning Medea's summoning or how she's teaching magic.

1: as I'm certain a few people have pointed out Fate Lore seems to play fast and loose at times and
2: Medea's brand of magic was taught to her during the era of God's, pretty much by God's or at least empowered by them. Which is a completely different animal than what the Magi of the Grail wars era uses.
So I would say that pretty much gives Medea cart Blanche to do with it as she sees fit.

Who cares. The story is great and a fanfiction anyways.

okay this is official, fav and fllow instantly, i want to see how all this ends!
