Engrid said that Tiamat used the Aetheric Field Stones to hide something. You were tasked with investigating this matter. You met Egzen, who told you of a destroyed Aetheric Field Stone. She asked you to find out more about the Aetheric Field Protectors. The Aetheric Field Protectors carried Tokens of Unity. You brought the tokens to Egzen. Egzen asked you to try using the tokens on an intact Aetheric Field Stone. You went to the Aetheric Field Stone that Egzen specified. But you got caught up in a fight with the Beritra Army. Thankfully, Egzen arrived with her troop. You then reported back to Engrid. He said that Beritra probably started the Major Offensive to find what Tiamat wanted to hide.
