Divinity's Twilight: Rebirth

Seven centuries ago, the forces of order won the Illyriite War on the plains of Har'muth. Darmatus and Rabban Aurelian slew their elder brother, Sarcon, the despotic architect of the conflict, then sacrificed themselves to banish the cataclysmic vortex opened with his dying breath. The first advent of the Oblivion Well was thwarted. Even without their vanished gods, the seven races of Lozaria proved themselves capable of safeguarding their world.

Or so the story goes.

The year is now 697 A.B.H. (After the Battle of Har'muth). Though war itself remains much the same, the weapons with which it is waged have evolved. Airships bearing powerful cannons ply the skies, reducing the influence of mages and their spells. Long range communication has brought far flung regions of Lozaria closer than ever before. At the center of this technological revolution are the three Terran states of Darmatia, Rabban, and Sarconia, who have fought a near ceaseless campaign of 700 years in an attempt to best each other. The roots of their enmity lie buried beneath the wasteland of Har'muth, a place all three nations consider best forgotten.

However, an ancient power sealed within Har'muth has not forgotten them, and the descendants of those who fought on that field must now take a stand to rectify the mistakes of the past.
