In re-reading Return of the King, it is mentioned that the lineage of men began to fall when noble men began to intermingle with the lesser wild men and such. It seems there is a clear distinction between noble men and lesser men. There are the Dunedain, which are the most noble men still in middle-earth, and those who share their blood. The "twilight men" I believe they are called, such as the Rohirrim, and I would imagin the Men of Dale, which are not as high up as the Dunedain, but are still noble. Then you have regular men, such as those in Bree and the like, and then even lesser men such as the Wild men and Easterlings and Haradrim.
So we are told in Lord of the Rings that the noble blood of men got mingled with the blood of lesser men and thus was weakened.....but where did these lesser men come from? Is there any mention in the Silmarillion of their creation? If all men were noble at the start, and there were no seperate lesser men...then who did they "mingle" with to dilute their noble blood?
There may be some Silmarillion quote that will totaly put this to rest, but it seems to me that Arda had two classes of race....lesser races, such as lesser men, the hobbit like creature that golem was, those Ghan-buri-Ghan people, ect, and then races of destiny, men, elves, and dwarves. (Hobbits might count as a lesser race themselves...I don't know).
From what I understand the Gods (valar) put the Noble races in place....but the best I can figure is that other lesser races just naturaly evolved in Arda right along side those awoken by the Valar. Would this mean that those of lesser races do not get to travel to the undying lands? Or are not favored by the Valar (the notable exceptions being those that prove themselves such as Frodo and Bilbo)
Just a thought.
