So far I have:
Lifen (Jiyel Scholar), Chinese name meaning 'beautiful fragrance', because she's a botanist who is going to romance Emmett
Isabeau (Revaire Widow), named for the character in Ladyhawke
Amalthea (Wellin Countess), named for the Last Unicorn, romancing Lyon for the sake of a 'the lion and the unicorn' joke
Melisende (Arland Princess), chose it as an Old Norman name that would fit very well with 'Constance' and nicknames to 'Mellie', which I thought was adorable
