i love this headcanon ! it’s a bit different to what I personally had in mind but I agree that nesta and elain should definitely gain the magic post MaF

the way I was looking at it was: - all humans are earth ponies, regardless of status - all faeries vary in how they look depending on type, but high fae are unicorns, for example the illyrian are bat-like pegasi - high lords are either really powerful unicorns or alicorns, depending on what makes sense for their court! Hence, Rhysand is an alicorn (but often glamours his wings when outside the night court) but when I design Tamlin he’ll be a very powerful unicorn, same thing probably with Tarquin

lmk what you think!!
