Summoned into a Magical World at Max Level AMW

As a hardcore fan of the online game Light of Glory, Rennes has devoted ten years of his life to become the most powerful Mage character. Crowned with titles such as "The God of War", "The Strongest Mage in History", "The Arcane Master" and so on, he has maximum levels in the five main branches of magic - elemental conjuration magic, light magic, dark magic, time magic, and space magic - as well as in every other type of magic in the game, and has achieved maximum level in all skills.
Upon reaching the Pinnacle of the Pantheon, the game world collapses and a black hole appears in his room, sucking him inside. When he opens his eyes again, he finds himself in a strange world surrounded by devoted worshippers. "O Honorable God of the Game, heed the call of your most faithful. Come to us and protect us."
