My idea was that Drawcia created Vividria and Paintra, abandoned them and tried to wipe their memories of ever knowing Drawcia, but it didn't work entirely. So they vaguely know who Drawcia is, but only know her as their "creator" and nothing more. Always curious on who may have created them, and always wanting to know. Drawcia wanted them to forget her entirely because she didn't want them to suffer and know that the one who made them was "evil". (If that makes sense)
