Why did Athena go to Ithaca?

Athena went to Ithaca to assist Odysseus's son, Telemachus, in his quest to find his father, who was missing after the Trojan War. Disguised as a mentor, she encouraged Telemachus to seek knowledge about Odysseus's fate and provided guidance in confronting the suitors vying for his mother's hand. Athena's intervention was crucial in helping Telemachus grow into a strong leader and ultimately reuniting him with Odysseus.
