Once Sieglinde agrees to explore the outside world, Ciel and Sebastian take her to the Emerald Castle’s basement, claiming it’s the gateway to new realms. Sebastian explains that an Emerald Witch’s responsibility is to forge the magic circle.

During their exploration, Sieglinde discusses the Werewolves and the dangers of miasma, explaining its detrimental effects on humans. She notes that while miasma was once plentiful and perilous for people, it served as a magical boon for beasts. The decline of sacred magic, which once thrived, resulted in the degradation of both werewolves and witches’ powers.

The werewolves implored the witches to recreate this vital miasma, vowing to protect the woods, which would later be recognized as the Werewolves’ Forest. In their quest for this potent magic, Sieglinde ultimately devises a spell that can generate dense miasma indefinitely, a feat that Sebastian acknowledges as a critical historical lesson.

The narrative thickens when Sebastian reveals a concealed lever, unveiling a hidden passage that allegedly leads to the “outside world.”As they enter this mysterious chamber, Sieglinde is taken aback, discovering an impressive array of gadgets and monitoring systems tracking the villagers’ whereabouts through amulets.

These amulets turn out to be transmitters, further shocking Sieglinde as she comes to grips with the implications. The group descends further into a lab that appears to specialize in chemical manufacturing. Suddenly, they overhear the village crone addressing a gathering of what she claims are Werewolves, announcing that Sieglinde has accomplished her task with the miasma.

Demanding clarity, Sieglinde is approached by the werewolves, only to discover that they are merely humans in costumes. Additionally, the miasma is revealed to be a chemical weapon, a poisonous gas masked by folklore and lies. Ciel exposes the elaborate facade, shattering Sieglinde’s understanding of her reality, while the village crone confirms that her creation, dubbed “SuLIN,”is the most lethal gas known to history.
