Rise of the Red Harbinger

Two thousand years ago, five Harbingers were sent forth by The Orijin, their god, to fix mankind. Once the Harbingers succeeded in their mission, Jahmash grew jealous of the other four Harbingers and turned against them. Before he could kill all of them, they trapped him on an island, knowing his deathly fear of the seas, to spend the rest of his existence in exile.
Now, centuries later, chosen Descendants of Darian find themselves with magical abilities and black lines on their faces, tasked with saving mankind from Jahmash's return.
They must learn to use their mysterious powers, which are specific to each of them, while being hunted by their own king's armies. Time is running short for the Descendants. Hunted by the very people they are supposed to protect, can they save Ashur from its greatest threat: The Red Harbinger?
