I liked
Raven Peony at first but in reality I wouldn't like two words as a name, and it seems like it would mean 'black peony' and I don't think black peonies even exist.
Raven Toulouse sounds cool but again, two words aren't great and Toulouse as a name is too Aristocats. And Luah reminds me too much of Luau, so I pick
Raven Talise.
If I could pick any middle name:
Raven Gaia,
Raven Gwyneira,
Raven Brenna,
Raven Kiera,
Raven Cerridwen,
Raven Ofelia,
Raven Leila,
Raven Lorelei
