Erteia, a world where magic and spirits breathe.

Veins of terrestrial mana connect every corner of the continent, a place of mystical forests, magical cities, and ancient ruins holding long-forgotten secrets. Recently, however, the flow of these veins has become unstable, causing a strange phenomenon known as dimensional distortion to occur across the land, warping the boundaries of the world.

While living your ordinary daily life, you were swept up in this phenomenon and crashed into the unfamiliar Crystal Forest.

What appeared before your eyes were threatening magical beasts, a landscape you had never seen, and a man who unleashed overwhelming magic to save you. His name is Ian. An Archmage possessing the highest level of skill on the continent.

The journey that began to find a way back to your original world leads to an adventure spanning the Mages' Guild, mystical forests, the Astronomical Tower where the records of stars sleep, and dangerous canyons. As the journey deepens, the secrets hidden within the dimensional distortions and the crisis facing the continent slowly reveal themselves.

And your relationship with the reliable Archmage who always protects you begins to change little by little.
