Fresh off a whirlwind tour of adventure, Ys: The Oath in Felghana opens with Ys series heroes Adol and Dogi as they make an unannounced visit to Dogi’s hometown of Redmont in the land of Felghana. It quickly becomes apparent that things have changed dramatically since Dogi left years earlier. Hordes of violent monsters roam the outskirts of town, a long-dormant volcano has suddenly become active again, and the new lord of the land has been taxing the citizens heavily. As Adol and Dogi begin to search for the sources of Felghana’s recent struggles, each clue found leads them closer to the disturbing conclusion that these events are all somehow linked, and it is only they who can save Felghana.
