Sauron: Mordor Orcs
built 274 days ago
Mordor, surrounded by high mountains, was very defensible, and undoubtedly Sauron chose to make it his fortress because of the advantages offered by the geography. But Gil-galad had few if any resources for maintaining a lengthy siege so far from Lindon. Numenor had no bases in the area (Pelargir would not exist for another 600 years), and the only peoples in the area were unfriendly (except possibly for the Ent-wives, who may have been willing to support the cause, but might ... have stood aside).

Sauron gradually rebuilt his forces, gathering hosts of Orcs and other evil creatures. He extended his influence over the Men of Rhun and Harad to the east and south of Mordor and he set himself up as their King and God.

If the Orcs required 90 years in which to increase their numbers, would Sauron have utilized that time to make inroads with other peoples? For example, how did he gain the trust of the Gwathuirim, especially those living in Enedwaith and Minhiriath? These Men helped Sauron during the war, but did they simply flock to his banner when he showed up with an army of Orcs, or did he perhaps spend time among them, winning their trust and playing to their fears and resentments. The Gwathuirim felt threatened by the Numenorean settlements and timber industries. The had been raiding Numenorean lands since Anardil (Tar-Aldarion) first built Vinyalonde in the late 800s.

G[A]ndalf's dark counterpart, Saruman, is a good wizard gone bad, who sells out to Sauron and turns his wizardly domain, Isengard, into an industrial and military powerhouse. Saruman perverts his powers to produce a bigger and more fearsome variety of Orc, and tears up the formerly pastoral countryside to make way for belching factories of evil that darken the sky over a decimated moonscape. There is a scene in the movie, as Saruman takes a tour of the new facilities, where he orders his misshapen underlings to "pull up every tree," that perfectly expresses the ideology of the bad guys.

Ar-Pharazon comes to Mordor with a great force and demands Sauron's surrender. Sauron submits to being taken to Numenor in hopes of bringing about their defeat by other means. In time he becomes a trusted counsellor of Ar-Pharazon and begins to corrupt him.

At the end of the Appendix - The Rings of Power - it was pointed out that Sauron - the Dark Lord of Mordor - was predominantly associated with Fire. Indeed, it might be hypothesized that he was a 'fire spirit' [see discussion, The Rings of Power.]
