In the third world (Chapter 6), in Sage Yulyana's sidequest to get the Conjurer Asterisk (after awakening 2 crystals) you learn from Dark Knight Alternis Dim, Templar Braev Lee and his wife/Edea's mother Mahzer Lee that the Edea of that world is dead.
However, at the start of the chapter, in a side quest before awakening any Crystals, Black Mage Ominas Crowe was expecting Edea to arrive to serve under his command. Before the fight with Knight Argent Heinkel, he questioned why Edea wasn't with Crowe.
After beating Braev Lee, he said Edea's sword was sent back to after her death. I can't think of why Ominas or Argent would have given a false report considering they just fought Edea and lost, or even how they got a hold of third world's Edea's sword, yet not show any surprise that Edea was actually alive (unlike Braev or Mahzer).
So I am wondering, when did Edea of the third world die? And were the Eternian Sky Knights forces in Caldisla not informed?
