Long ago, at the very center of the island stood the Ruins of Light, a beacon whose radiance reached across the entire land. The ancient people stored their most precious records here, but when the ruins collapsed, those records shattered into countless fragments and scattered to the farthest corners of the island. For centuries, no one could read them --- until the day the explorer Brue arrived.
The ruins have long since lost their original shape, yet beside them lies a heart whose light has not faded. Its core remains locked away, and no one alive remembers what sleeps within.
Now, the journey falls to you. Join Brue in exploring the Heart of Light, and face the memories sealed inside.
