On the continent of Aida, there exist two nations: the Doralis Empire, which governs the day, and the underground sorcery city of Orva, which controls the night. The dimensional rift, passed down between the two nations, was unexpectedly opened by a powerful energy wave when the leader of the sorcery city perished. Originally engaged in mutual conflict, the monsters of the sorcery city began to set their sights on the Doralis Empire, seeking more resources to strengthen their military power. Following the opening of the dimensional rift, the monsters started their invasion upwards. To avoid depletion of their spiritual energy under sunlight, they summoned eternal night, shrouding the entire continent of Aida in darkness.
The peace-loving Doralis, who cherishes sunlight, lost three strongholds in succession after being attacked by the sorcery city. The Grand Magician Alje, along with numerous mages, erected a barrier outside the castle to temporarily secure its safety. Meanwhile, his brother, Vernal, took on the role of Legion Commander, rebuilding various military units from scratch and personally leading troops to reclaim lost territories.
In the game, players assume the role of the Legion Commander of the Sorcery Empire. They must gather coins through crops in the farm, allocate economic resources to enhance soldiers' abilities, and employ real-time strategy (RTS) deployment to recapture territories occupied by different monsters.
