Exactly.
In Chapter 13(Ren-eunion),Anathea said that we were very close to Maria...so,if we could do more time-travel and getting in Indriad's story,would we do something very important?
Honestly,I don't think that we will can save her:if in our time,Maria lost her memories with Indriad,we have to remember that Vitus lost Anathea,so he returned to be Indriad
