It is the late 13th century and Europe is still reeling from the shock of the all-conquering Mongol Hordes. But, just as the lords of the West breathe a sigh of relief, another threat looms on the horizon; literally. Strange ships have been sighted all along the Atlantic coast, bearing symbols never before seen in the known world; winged serpents and grinning skulls. As the sun sets on the shores of Morocco, Portugal and Ireland, the largest fleet that has ever set sail approaches land, ready to invade in the name of bloodthirsty gods.

For the first time ever, Paradox Development Studio is introducing a fantasy scenario in their strategy games with the Crusader Kings II: Sunset Invasion DLC for the critically praised strategy/RPG Crusader Kings II. It is a fantasy scenario where the blood drenched Aztec Civilization arose early and spread like a virulent plague, learning of Europe from exploring Northmen. Prepare to defend all you hold dear against the Sunset Invasion!
