While a primal that resembles the Sylph's may be a better fit, thematically, I do like the idea that they made Ramuh the ultimate, nurturing, wise grandpa, which is a great foil for the playful little pranksters that sylphs are.

Fairy is an old summon from other FFs, but she was a healing summon. I guess Scholar would have been written quite differently if Fairy existed as a primal.
