Great Orcish Wars

The Great Orcish Wars, as they are most commonly called, were the series of catastrophic invasions into southern Orithea by the armies of the legendary orc warlord Gol Garga. They began in 1231 CV with Gol Garga's initial attack against Vastemar, and ended twenty-two years later in 1253 CV with his sudden, unexplained disappearance and his leaderless horde's final defeat at the Battle of Crow's Gorge.
Although the horde was ultimately defeated, the damage inflicted on human and dwarven civilization in Orithea was immense. All the lands of Vastemar and Sularia--an enormous expanse of territory whose kingdoms had held firm against countless other orcish assaults over ages past--were completely overrun and remain under orcish domination today. Millions upon millions were killed, enslaved, or forced to flee north as desperate refugees. Kelimaria was ravaged by marauding orcish armies, its three-century old Sultanate collapsed, and its fragmented emirates now teeter on the brink of civil war over the question of the sultanal succession. The lands of Dranuria and the Sornele were even more thoroughly devastated and now lie in war-torn disarray, anarchic and bandit-plagued where they are not occupied by the dwarven armies of Kuzul-Kadrin.
