Prologue

Merlin had been waiting long enough. The time had come for him to interfere. He had stood by when Voldemort rose to power the first time, he had done nothing when a baby Harry Potter's life had been threatened, he had even ignored the fact that Voldemort had infiltrated his precious school by way of a stuttering teacher. But the time for silent observation had come and gone.

When the school had been formed, Merlin along with the four more well know founders had done everything in their power to ensure that it would be a safe place for students in the far future. But this Dark Lord was ruining the protection the school had offered in the past. It was just a matter of time before his plots and schemes actually found a way to take down the school and, afterwards, the entire wizarding world.

In the centuries he had lived, Merlin had watched over the world, especially his own kind, but now a new threat was presenting itself in Harry's fourth year at Hogwarts. Though he didn't know what events would take place, he knew that they would end in the resurrection of Voldemort. Merlin swore he would not let this happen. To keep a closer eye on his beloved school and the young residents, he decided to break his tradition of watching and waiting and take a teaching position at Hogwarts. His wand magic was not nearly as powerful as his raw natural talent, but he knew enough to teach these students the art of defense.

Years had passed since the fall of Camelot and the death of Arthur, but Merlin always had hope that his return would be right around the corner. His King and greatest friend would rise again when the world most needed him. Perhaps that time was closer than even Merlin could imagine.
