In the silent decades of the 17th century, the island of Eldoria became the heart of whispered legends about riches untold and treasures unclaimed. The heartbeat of the island itself resonates with the echo of footsteps searching — plotting — discovering. Yet, the richest tale is of the treasure that remains unsolved in its slumber.

The first mention of the treasure surfaced in a faded journal, discovered in the depths of the Jinsoo Library. Scribbled notes mention a map, half-lost to the tides of time, describing an underground vault protected not just by locks and traps, but by riddles carved into stone that guard its secrets.

Breaths between heartbeats… the interval of time that stretches between moments like whispered prayers or forgotten thoughts. Here lies the secret; the rhythm of the heart, the interval of silence, awaiting the next pulse of inquiry, the next breath of discovery.

Historians believe the treasure could encompass gold and precious stones, but what most intrigues scholars is a legend calling for a third key — not a physical one but a cipher to decode the language of the ancients etched into the walls of the vault.
