I tried to keep my names lore-appropriate.
So my main is a Keeper, Seraph'ir Vhinah.
I usually go with 'Seraphor' everywhere, so changedthat to 'ir, one of the suffixes male keepers have (specifically the sixth-born male, so I guess it was a huge litter)

Made a black cat to go for the black-skin/yellow-eye combo for BLM, so to reference the best Black Mage in the franchise, Vivi, I decided to throw 'life' into a translator and came up with Hinah in... I forget if it was Navajo or some other native american, and because Miqote keepers have a tendency to stick a H after consonants, I stuck a V on the front of it too.

My alt Serafo Inochi, is just a Raen version of 'Seraphor' and 'Life', Raen of course being direct Japanese names.
