1993. Harry Potter is about to begin his third year at Hogwarts, but for Eric Clapton, his first year is only just beginning.
Two years ago, Eric woke up in the body of an orphan in London and quickly realized that he had been transported into the world of Harry Potter. Fortunately, he didn't arrive empty-handed.
Along with his new life came the Strongest Wizard Sign-In System. For two years, it remained completely silent, until the day his Hogwarts letter finally arrived.
[Ding! Sign-In successful.]
[Reward acquired: Top-Tier Magical Power.]
From that moment on, every important place in the wizarding world became an opportunity. The Leaky Cauldron, Diagon Alley, Hogwarts, each new Sign-In could grant Eric powerful rewards, new abilities, and another step toward becoming an extraordinary wizard.
And unlike everyone around him, Eric already knows what is supposed to happen. Sirius Black has escaped from Azkaban, Peter Pettigrew is still hiding in plain sight, and Voldemort's return is drawing closer.
But Eric has no intention of quietly following the original story. Armed with knowledge of the future and a System that rewards him for exploring the magical world, he intends to carve out a path of his own. After all, if knowing the future is already an advantage...
why shouldn't he use it to become the strongest wizard alive?
