[Galadriel55]

To make the story fit more into what was created by Tolkien, you could either make it happen a few generations down, or in a place that we don't know much about (eg somewhere far east, south, or north). That way you have room to invent something new.


PS: If it takes place somewhere far east, it might be advisable to make Khazzar an apprentice of either Alatar or Pallando, or just follower of the "cults" that they started.

PPS: If you want to create a continuation of any of Tolkien's works, I suggest concentrating as much on the style as on plot and cannonicity. He has a ot of philosophy in his works.
