tl’dr Lydia is a powerful summoner who cannot control her powers. She was locked up after using some minor magic so they know she’s magic, but not just how powerful she is. She’s schizophrenic, and each voice she hears is a channeled diety she can eventually summon. God, devil, lightning, FF, Bahamut, etc. 

Celes = celestial being (bahamut-ish? / celestial magic)
Lucy = lucifer (fire)
Raine = Ramuh (lightning)
Levi = leviathan (water)
Terra = Terra (earth)
