Golden Springs of Sonia Island.

The Golden Springs of Sonia Island first appear in Volume 2 as a mysterious, sunlit oasis hidden within the treacherous mists of the Sonia Sea. Across the series, these springs evolve from a mere geographical curiosity into a pivotal nexus of Beyonder power, tied to ancient rituals and the lingering influence of the Primordial One. Their waters, imbued with latent spirituality, become central to key plot developments involving Klein Moretti and the Tarot Club, as well as the broader struggle between hidden organizations vying for control over the island's secrets.
