Absolutely, glad you asked! 😀

542 AS: The few remaining Khymians are hiding underground as Ferexia takes over their land and multiplies. All hope seems lost, when Khymia herself descends from the sky to intervene. In a great wave of unstoppable light, all living creatures vanish from the surface of Khymeria. The Ferexia occupation is finally over, but all wildlife is gone from the land as well, leaving only Feral Spirits, ghostly remnants of animals that exist only partly in this realm. The historic event becomes known as the Obliteration of Light

With your question, you have stumbled onto something. In the accepted history, the Obliteration of Light is accredited to Khymia, the hidden and all-powerful goddess of the Silvershield. But in the Angel's profile, she clearly blames herself for the horrible event. What does all this mean? Perhaps time will tell.
