Draken, what would need to happen for the twins to be released from dronification?
(And where did that happen, anyway? )
Also... their mother's injured but alive, right?
They could be released by either parent (Erscheinung or Reene) or the drone-form could be purified.
They are still in there, locked and comatose. Theoretically their inner minds could wake up and talk to and even convince Erscheinung or Reene to release them.
