Hogwarts: Echoes of Fate

In 1945, Grindelwald was imprisoned in Nurmengard, but he did not fade into obscurity. The Grindelwald loyalists remained active in Europe. In 1956, Dumbledore became headmaster of Hogwarts. In 1971, Rock came to Hogwarts on the orders of the Grindelwald loyalists. By fate's design, he met the two most important friends of his life. But Rock felt that something was off about both of them. Why did one claim to come from another time and space? And why did the other keep muttering that if he got to live again, he would make the most of it?

Faced with two of the most powerful wizards of the past century and their friends, what choice should Rock and the others make?
