Can Relax - Calming (Skadi)

"What's she doing?"

"Just like you see, she was beautifying the graves of her friend."

"That's not what I'm asking. Why is she doing that herself?"

At the back of North Coast Palace, right on the edge of the cliff, Skadi is building more beautiful graves for the five existing graves.

That makes Ars questioning Skadi's doings.

"Well, because she wants to build it herself, of course."

"In a world where the human body breaks down into mana particles and leaves no remains, why did she build a grave in the first place?"

In Abyssal Terra, only Black Hunter has their body decomposed. That is because they use dark mana, source of forbidden power from the Older World. 

Even so, as much as possible their bodies should be burned and cremated.

Because of that no burial system was in place, as Skadi was doing.

World Stone replaced the burial system of the heroes of conquest expedition.
