Tyrion invited Kinvara to Meereen during the time when Daenerys was still missing. Kinvara arrived, and promptly disturbed Varys by revealing that she knows nearly everything about his past. She told Tyrion and Varys that Daenerys was chosen by the Lord of Light, R'hllor, to lead the fight against the coming darkness (White Walkers).

She deployed other red priests and priestesses to spread word of Daenerys' special role, but we have a sneaking suspicion that she'll return. Personally, we'd love to see her and Melisandre meet face to face.
