The game ''Dark Horizons'' takes the player to the very beginning of the Second Era of Enosta Universe, about a century before the disappearance of the legendary cruiser ''Talestra''.
This chronicle begins on a date which became a judgment day for many races of the Galaxy, when a new form of Mirk came into existence, later to be called ''De'Khete''. The player takes part in these events as a member of the race of Guardians. Once human, now transformed by the Mirk, the Guardians created their own world and found the strength to confront the incoming menace.
''Dark Horizons'' is a look at the past of the world through the eyes of those who are currently the spawns of the Mirk, and who's victories could give hope to many. During the missions, the player will have to go through a long and exhausting defense of the place that became the second home to the Guardians, fighting alongside the people transformed by the Mirk, who's powers lay beyond human comprehension.
This is a story about the warriors of Vattar Ama'Dan fortress, called to defend the construction of the ''Light Core'', which would save billions of lives later on. Their heroism is immortalized in the Tarr Chronicles, the dark annals of the dying galaxy of Enosta.
