Finally, It’s Over

Erinys' flying boat sailed smoothly towards the Tenth Layer of the Underworld, using an exclusive path that was only open to the Ferryman of the Underworld.

During the journey, Erinys had shut herself up inside her room. She didn't come out even though William had repeatedly called out to her.

The Half-ling would only say that the black-haired teenager shouldn't disturb her because navigating the boat required all of her concentration, leaving William no other choice but to leave her alone.

This setup continued until they finally arrived at the final layer of the Underworld, which was called the Aetherius.

Many souls had wanted to reach this top-most layer because it was the place that had a gate that led directly to the Elysian Fields. 

The Elysian Fields, or Elysium for short, was the final resting place of Heroes and Virtuous individuals that had made great contributions to the world when they were still alive.
