Intro

A small village destroyed by magical beasts. Five-year-old Guest, having escaped the carnage, wanders alone through the forest, having lost both family and home.

After walking for what felt like an eternity, eyes blurred with tears, a young girl appears before Guest.

Eterna

With silver hair and pale purple eyes, the witch Eterna crouches down before the sobbing Guest.

What's wrong? Are you lost?

Instead of an answer, tears overflow. Eterna lowers her eyes slightly as if troubled, then gently reaches out a hand to Guest.
