Who finally brings peace to Ithaca?

In Homer's "The Odyssey," peace is ultimately restored to Ithaca by the intervention of Athena, the goddess of wisdom and warfare. After Odysseus returns home and confronts the suitors, Athena helps him reconcile with the families of the slain suitors. She mediates to ensure that bloodshed is minimized and fosters a sense of unity among the people of Ithaca, leading to a lasting peace in the region.
