She's introduced late and isn't very interesting. She really doesn't have a personality to speak of and feels like another victim of multiple writers pulling in different directions.
I got her into the party pretty early, not long after I got onto Groundbreaker. You're right about lacking a personality, but ... well, no more than the others really.
I finished Parvati's love-quest and man... really, whoever wrote that shit has no inner life. At all. It was just utterly vapid from start to finish. I was hoping there would be some kind of twist but nah. Go drinking, introduce them, buy soap, get casserole, get pie, buy something nice to wear, arrange date, it went well, everybody's happy, the end. Like... how much more vapid can you get?
