Some Fe heroes tidbits:
-Those swirly intricate designs? Celtic knots. I appreciate the detail in this. Alfonse, Sharena and Anna all have armor and designs similar to Celtic armor as well.
-The tree symbol on the relic that you summon different orbs from is a reference to the Celtic tree of life. Which is cool considering you as a Summoner bring “life”
-The name “Alfonse” derives from the Latin name “Alphonso” which means “Noble and Ready”. Quite suitable for his character don’t you think?
I’ll add more later when I feel like doing research. Feel free to correct me or add more
