What happened to Helen of Troy?

Could you elaborate on the fate of Helen of Troy? Her story has captivated audiences for centuries, but I'm curious about the specifics of her journey and its aftermath. Did her beauty truly cause the Trojan War, and if so, what was her role in its conclusion? Did she face any consequences for her actions, or did she find a way to escape the turmoil she had inadvertently sparked? I'm eager to learn more about the legendary woman at the center of this ancient tale.
