OOOOOOOH OK THIS MIGHT BE A LONG ONE DEPENDING ON HOW MUCH I RAMBLE.
If you've been here awhile you'd maybe remember that before fe took over my life I was very very very much into persona. Specifically p3. And Akira was originally my silly little self insert that I had for ~10 years before she slowly became her own thing (partially into persona but DEFINITELY now). So. I think you know where I'm going with this (and if you don't that's ok too).
So yeah, the friends that I'm usually very vague about because I haven't fully fleshed them out in what I suppose is an fe au for them but just canon in my head is SEES. "Familiar" was a fun term I settled on rather than persona. And because fe LOVES their dragons I changed them all to be more dragon-like, though Akira's changed the least because Nike was already dragon-like to begin with. To adapt them more to an fe setting, they aren't fully physical beings, at least not outside of their home region. To summon them there has to be a similar power, such as dragon veins or tools invented to support that amount of energy, as summoning them without can be extremely dangerous if not fatal. While I haven't really decided on classes to base everyone off of, they have their Familiar, a weapon, and a general magic skill that is basically based off of their character in p3. For example, Mitsuru is a sword user who specializes in ice magic (she's also the one who takes the role of Queen after [REDACTED] dies because (a whole bunch of personal lore that would take forever to explain so tldr; just trust me)). Akira was originally a sword user who specialized in almighty magic, which I can't remember what I compared that to in fe but it's not important. She dabbles in some magic but focuses on swordsmanship. The fe-ified persona stuff merges with fates stuff in a post p3/pre-fates setting but the meat of my thoughts that I have about Akira are post-fates.
HI I could go on and on about this you have no idea how excited I was to talk about the LORE I'll leave it at this for now just know I'm kicking my feet and twirling my hair.
