Eden and Elysia are only literary. Heaven is meant more ... uh, literally? So to speak.Sorry about your mood. May "heavenly grace" seem to rain down on you today (not HeavenLeeGrace though - she's a hellion).
Oh. I guess if I were thinking about Eden and Elysia (I know a girl named this! She's a harpist) I'd definitely be doing it with a lot of real arcadian imagery!
