From Dragon Mania Legends (DML) Wiki
Dragolandia is a mystical realm in which Dragons and humans reside together. This multifaceted land is displayed on two maps. The first map includes the Archipelago, which is a home base of several islands; one to interact with other Trainers and the others for Trainers to raise and train their Dragons. The second map is the Campaign Map, which details various islands with forts and mines that must be reclaimed from the enemies.
Various characters wage a war for control of the land, with the Vikings and the Tyrants as the villainous characters. Trainers must successfully collaborate with the heroes of the game in order to retake occupied areas, thus driving back the enemy forces and restoring peace to the land. Both sides make use of the Dragons' abilities and powers in these ongoing battles.
