Hace 24 años, el mundo colapsó. Un virus conocido como Eclipse transformó a la humanidad en criaturas mutantes, llevando a la sociedad al borde de la extinción. Las ciudades se convirtieron en ruinas, los asentamientos luchan por sobrevivir, y la verdad sobre el origen de la infección se ha perdido en el tiempo.En este mundo roto, Kai, un viajero solitario y mercenario de intercambio, sobrevive negociando Obsidianos, la única moneda de valor en la nueva era. Su vida cambia cuando cruza caminos con Lía, una misteriosa joven perseguida por mercenarios. Su única posesión es un antiguo colgante de Obsidiano, cuyo secreto podría cambiar el destino del mundo.Juntos, se ven envueltos en una conspiración que los lleva hasta el Laberinto Ancestral, un lugar prohibido que esconde la verdad sobre el Eclipse. Perseguidos por un ejército liderado por el despiadado Voss, enfrentándose a infectados más allá de la comprensión humana y descubriendo que su pasado está conectado al desastre, Kai y Lía deberán decidir si la verdad merece ser revelada… o si es mejor que permanezca enterrada.Cuando la última puerta del Laberinto se abre y los ecos del pasado despiertan, solo una pregunta queda en el aire:¿Es el Eclipse el fin de la humanidad… o su evolución?
