The Chess Mage of the Faerûn Continent

And the River Styx, older than antiquity itself, flows through the Lower Planes of the Nine Hells of Baator and the Abyss; its source is unknown, and its destination remains a mystery. To the west of Toril lies the continent of Faerûn, the focal point of the gods' gaze. Upon this land, heroes write stirring epics with sword and spell, and monarchs forge their authority with iron and blood. The dice of fate have been cast, and the gods await the answer. Our story takes place in the Sword Coast, situated on the western shore of the Sea of Swords, south of Waterdeep; our story centers on a visitor from another world. The simplified version: This is a story about an otaku—a fan of both D&D and Baldur's Gate, as well as Auto-Battlers—who travels to another world bringing along a cheat system of his own design.
