In the colossal clash known as Ragnarok, the forces of Gods, Giants, and Dragons waged a battle against the fearsome Demon King Morroc, leaving in their wake a trail of destruction and chaos. In the wake of this conflict, the once-feeble race of humans flourished and emerged as the dominant force.

As time progressed and the wounds of the past began to heal, those who had survived the ravages of the great battle emerged from the shadows. The dragons, thought to be defeated, were sighted by a few brave humans. Meanwhile, Morroc, ever-vigilant and opportunistic, rekindled his thirst for power.

It is here that the adventure of RO begins anew.

In the latest version of the game, RO 2.0, players can traverse a vast and intricate 3D world teeming with diverse cities, untamed wilderness, and treacherous mazes. Characters of all stripes can unite to solve the countless riddles that abound in the realm of Midgards.
