I think most people realize by now that Ikona has been turned into a Hives asset by Salvathune's daughter (green eyed lady on the moon). Unfortunately, it doesn't seem like Zevalda has figured it out yet. It's likely he suspects something, which is why he sent Ikona to the far end of the tower. However, during the Witch Queen campaign the Awoke Queen says something about not trusting the guardians. I wonder if she used her Awoke magic to figure out Ikona has become a Hives asset. It seems like Moyra Salve may know more than the guardians about what is going on.
