Song of the Ancient Land location (Red Moonshade)

Clue

The children sang as they played. "It sounds like a song that is passed down to the Delain children. As I listen there seems to be some story behind it. Do you think it's a story of the past?" The monastery's priest smiled as he said this.

Story

"So those were the lyrics to the song that the Delain children were singing... That's shocking." The priest from Sacria seemed taken aback. "That song seems to be about the ancient people that lived in Feiton. I heard they all disappeared during the Chain War. Maybe their descendants are still living somewhere in the undergrounds of Feiton."
