I Possessed an Ancient Artifact

Armin was the chief apprentice to the best craftsman before he died in a fire., trying to protect the artifacts. One day, he woke up in a place with unlimited resources where he could craft to his heart’s desire.  He was content to live his shut-in life and stay away from civilization until one day one of his artifacts started glowing and connected him to the outside world. That was when he came to know that he had become an artifact with unknown class and potential. The world outside has also changed, to become one he no longer recognized. Dungeons and monsters had become a common part of everyday life and Armin’s life changed from that moment. He was once content to be left alone, but now his creations were capable of birthing incredible power. He had become an ancient artifact unparalleled in this world. But would he become a saviour or a punishment? That was yet to be seen.
