hey, there is a fic in which twilight invented some sort of magitech and she has a moving magic workshop which is powered by philomena. Rainbow can't fly very well and has PTSD and looks to twi for comfort. rarity is studying in the university for twilight's invention and is struggling and then twi takes her as a personal student. Also there was a part where twi was self levitating herself while sleeping in a boring meeting. Could someone please send me the name or the link to the fic. Thanks

This sounds awesome! I want to read this!

That does sound pretty cool, some searching around came up with this.
Would that happen to be it?

yes ! thanks sooooo much. I spent over two days looking for it
