The Drakai had long believed that their draconic heritage had marked them for greatness, with a number of previous emperors/empresses reigns being marked by ambitions to either expand Dranyas borders, or to further build up the territories they already had. This belief in their own greatness would eventually come to a head during the reign of Emperor Aldrithan Sothrath, who would launch a massive campaign to bring the world under the rule of the Drakai, through either diplomacy or force of arms. Fuelled by the belief that they were destined to rule the world as the Dragons of old had, and with the entire might of their armies at their command, the Drakai began mobilising for the war to come.
While their progress was slower than it was at the start of the war, the Dranyan forces continued to gain ground throughout Vraelia, managing to conquer the lands of the Minotaurs and Reshari, as well as much of southern Zemar, and reaching the eastern border of the Sun Elf kingdom of Helarion. With much of their home continent secured, Dranya set what forces they had to spare to the task of securing the continent of Imera to the north, though their efforts were slowed by the Helarion and Zemar still holding the land crossing between the two continents, as well as the Minotaurs continued resistance (which included harassing their ships, escaping with what ships and troops they could, and sabotaging as many ships and harbours in their territory as they could to prevent them from falling into Dranyan hands). While these factors only served to slow their inevitable arrival on the continent, many historians agree that these resistance efforts by the free people of Vraelia bought the people of Imera valuable time to prepare for the coming invasion.
When the Dranyan armies arrived in southern Imera, the fighting proved to be just as fierce as it was in Vraelia, covering the southern regions of Myrell and Athenor, the eastern border of the High Elf kingdom of Caelora, and along the eastern coast. Unlike their campaign on Vraelia, the Dranyan invasion of Imera was much less successful thanks to the early warning they had received, with their land invasion grinding to a halt after making slow progress, and the combined fleets of Athenor and Navalonia preventing their fleet from gaining ground on the east coast. Eventually, the forces of the Allied Kingdoms (consisting of soldiers and supplies from the various Human kingdoms, the Dwarves, the Orcs, and the High and Wood Elves) managed to push the Dranyan forces out of Imera, and began sending forces and supplies to aid in the liberation of Vraelia, which itself was overseen by an alliance between Helarion, Zemar, and Setymar (which had managed to hold its ground thanks to aid supplied by the Moon Elf fleets of the uncontested west coast), as well as Minotaur and Reshari resistance groups within occupied territories. Thanks to the efforts of the Allied Forces, as well as the efforts of those Drakai who wished to end the conflict from within, the Dragonscourge was finally brought to an end, with Emperor Sothrath perishing in one of the final battles of the war.
