A Wizard? No, I am a Scientist

DND, True Western Fantasy, Transcending to Another World.

A scientific expedition to the Arctic unexpectedly encounters a mysterious crystal from the Earth's core; a supernova explosion tears apart spacetime, hurling physicist Linge into a magical world where two moons hang in the sky. Here, he discovers that the crystal is actually the source of boundless magic.

In order to survive, he joins forces with Erwin, a young magician burdened with the blood feud of his family, and embarks on a perilous journey south.
