Fantasy mixed with sy-fi

(No this is not a part 2 to something, this is part one of my story. Also just saying, its probably gunna be really cliché) the great sorcerer of Niand likes to be called the professor. When him and his nephew send a friend of theirs home-as in here *awkwardly moves hands around* Earth, our plane of existence u kno...here. They find that they sent them home a little too late so now they must find their friend-the one they just sent here-and hope that they can remember how to set their plane of existence back into "normalcy" because sometimes when you pass through planes, you loose your memories forever. Unless you can control time. Which is what the professor and his nephew can do.
