I got some, actually. XD Wolf as an animal, The Moon as a Tarot Card, Wrath as her Deadly Sin...not sure on her god/goddess motif yet. Thinking Persephone because she's the underworld queen...but she's also a damsel-in-distress, which Monica isn't. Maybe...Ares? Hecate? XD I think Roc is Artemis, and Freya is probably Hera, Demeter or Athena. Leo...Aphrodite or Apollo, Nao...Hades?
How about...flower motifs? What flower do you guys think fits each character nicely? Freya's is obviously Cherry Blossom. XD Monica...um...something that's not a daisy, since it's too clean and innocent. Poppy? Rose? Iris? Love-in-Idleness?! (Wait, that name also fits as Leo's flower. XD)
