The map on the jade disc led them to the Heart of the basin on the seventh day. It was not what any of them expected. There was no grand pyramid, no sprawling city of gold. Instead, they found a single ceiba tree of impossible proportions, its trunk wider than a cathedral and its canopy so vast it created its own weather system, clouds forming and dissipating among its highest branches. The roots plunged into the earth like the fingers of a buried giant, and where they surfaced, the ground hummed with a vibration that Elara felt in her bones. Embedded in the trunk at eye level was a hollow perfectly shaped to receive the jade disc. Elara hesitated. The visions had shown her what the Koru had protected: not treasure, not weapons, but a living archive encoded in the biology of the jungle itself. Every vine, every root, every bioluminescent thread was a strand of data in a network that had been recording and preserving knowledge for thousands of years. Inserting the disc would unlock the archive, making it accessible to anyone who reached this place. 'The world is not ready for this,' Marcus said, reading her expression. 'It was not ready when the Koru made their choice either.' Riku knelt among the roots, pressing his palm to the humming earth. 'They did not hide this because they feared the knowledge. They hid it because they understood the responsibility that comes with possessing it. The question is whether we understand that too.' Elara looked at the disc, at the tree, at the faces of her companions. She thought of her grandmother, who had found this place and chosen to leave it untouched, returning home with only a journal full of drawings and a secret she carried to her grave. She understood now why Adela had never published her findings. Some discoveries do not belong to the discoverer. Elara placed the disc back in her pack. The jungle exhaled, and the canopy above them rustled with what might have been approval.
