Astrea and Moriganne spoke about the prophecies that had been passed down from generation to generation. Nobody knew about them until they revealed them at that moment in the hall. At first, everyone who didn't know what happened thought this meeting was to discuss the prophecies until they found out the prophecies had come true.
Moriganne showed the reports about the missing people, including Ermaine. The dead bodies and countless corpses of demonic beasts that the templars found.
Astrea revealed the expedition that she did with Moriganne and the others to the Blackcliffs. She told them what had happened, and the gruesome experience they had over there. Everyone was baffled when they heard that and couldn't believe they went there and survived even though they fought countless of Corrupted.
"We wouldn't survive if it wasn't because of Sanya," Moriganne revealed as she looked at her hands on the table.
