In the year 2197, Earth’s oceans have been drained to power interstellar expansion, revealing a vast, ancient structure buried beneath the Pacific basin: the Subnaut Archive. Believed to be a pre-human repository of memory and consciousness, it begins transmitting encrypted signals that affect the minds of those who listen. A small crew is sent to investigate—but the deeper they go, the more their own memories begin to rewrite themselves.

In Echoes of the Orphanet, Lira Auron and her fellow Echo-Tuned—beings harmonically attuned to cosmic frequencies—must confront The Dissonance, a primordial force consuming reality through silence and entropy. Guided by a forbidden celestial composition known as The Orphanet, they sacrifice fragments of their identities to interpret its melody and combat the unraveling of memory and sound. Amid haunting harmonies and existential sacrifice, they orchestrate a final symphony to preserve the fabric of the universe, discovering that unity through resonance may be the only way to silence the void.
