Looks confident, intelligent, lethal and gorgeous. I'd love it if she were a natural leader, maybe even led one of the Inmortal factions in the War. But also capable of showing warmth and love in private or with those she trusts.
Also invisibility is not to scoff at could mean so much secret info, specially if she can even turn inmaterial to pass through things, perhaps also turn her soul and mind invisible to be immune to other Inmortals.
Oh that is a great thought. How much invisibility can she generate? I'm so excited to see that.
