Vanille here will be getting possessed by Nala - she's already fairly well attuned to healing. And pretty warm-natured and such. And, well, she's seen a lot of fighting, so she'll kind of want to calm things down.

My alternative choice is Faeren because her eidolon is affiliated with Earth and it's not a far leap of logic, but I think Nala fits her more.

I may be just a touch slow getting started on things, but I'll backtag! ♥
