I'm not sure how useful this is now that it is after the fact, but during the confrontation with Ramaa I was able to confirm through an Advanced Libra that she does indeed have, "strong ties to Vaikuntha, Crystallis and Earth."
If it's of any consequence, it seems as though her plan, at least at the time, was to "use the Heroes of Light to weaken the Melodies keeping Vaikuntha together and revive Narayana, the Calamity from the Skies."
