A Sonia Sea island with an extinct volcano, hiding a black palace in its depths.

Isla con Volcán Extinto first appears in Volume 2 as a remote Sonia Sea island whose extinct volcano conceals a black palace, establishing it as a hidden sanctuary and potential site of ancient power. Across the series, the island transitions from a mere geographical curiosity to a nexus of forgotten history and mystical significance, its volcanic depths serving as both a literal and symbolic gateway to deeper mysteries. Its evolution mirrors the broader narrative's shift from surface-level exploration to profound revelations about the world's hidden architecture.
