The Tomb of the King Uncrowned

I've done a lot of research into an ancient king that ruled over what we now know as Erenen during the Third Era. This figure is only known as the King Uncrowned.
I believe that if we can uncover the tombs of his most prominent knights, we can find the tomb of the king himself - and all the treasure within.
