The First Echo was only the beginning.

In Siren, the journey continues as Robert, Camille, Isaac, and Stellan find themselves thrust deeper into a world unraveling. Haunted by visions and pursued by monsters that should not exist, their fragile alliance is tested by loss, betrayal, and the weight of impossible choices. At the heart of the chaos lies the EchoStone, an ancient force that bends past and future into a single, shattering present. Worshipped by some, feared by others, it reveals truths meant to stay buried… and threatens to consume all who touch it.

As rebellion stirs and the armies of LOT close in, the fight is no longer for survival alone, it is for the very thread of time itself.

The First Echo called them. Siren will break them.
