The two nations, Millena and Rain, have had a long history of terrible wars and skirmishes which spanned over a thousand years. During those terrible times, the monsters which inhabited Lette Plane, a large undeveloped land between the two nations, took advantage of weakened defenses and mounted attacks on both capital cities. The threat posed by these monsters forced leaders of Millena and Rain to come to a ceasefire agreement and soon after, diplomatic relationship followed.

200 years have passed since the last Great War. Both nations have prospered and grown in stature again. The discovery of a new magical energy source called Elda Stones in Lette Plane has caused both sides to venture once again into Lette Plane as they seek to expand their borders.

Will the fragile peace be shattered and hostilities renewed? Or is there more than meets the eye about the origins of the Elda Stone? Come find out today and join other eager adventurers in the fantasy world of Deco Online!
