Flipped through the FB&WIs again today, good book gotta get it one of these days. Anyway, I was wondering why under the Nazgul concentration was made on the two Numenorean Kings and yet ther was no mention of Khamul? According to one of the resources I have Khamul, an Easterling king, sometimes called The Black Easterling or Shadow of the East, and second only to the Witch-King in rank. He was the leader of the Nazgul who sent to Dol Guldur. Why no mention of him?
Now, I didn't go deeply into the new description of the Nazgul, but as the new ones were listed as BNs it just did soud right. If I have miised something then let me know.
