As the new overlord it's your task to gain all the strength and skills you can, harness the power of the Minion horde and take back what is yours. In recent days a new power has arisen, known as the 'Glorious Empire.' Based in Roman-like legionary tactics, the power of this new enemy is being used to take over all the relinquished territories of the old overlord, and to extinguish all the magic in the land in order to weaken all potential enemies. This child is obviously special, but time is short and he has much to learn. Here they find a male child the likes of which has not been seen since the coming of the original overlord. Sensing that something is afoot, the Minion horde has made its way north to the town of Nordberg. Yet change finally appears to be in the air.

The comically evil, but still deadly gremlin-like army known as Minions are lost without a leader to focus their chaotic power for good, ill or both. In it the original overlord is no more, and in his absence the order of things have changed dramatically. Overlord II picks up right where the previous game left off.
