From J.R.R. Tolkien's Middle Earth, "Sauron" is a simulation of the Battle of Dagorlad from the 2nd Age of between Sauron and the forces of the Free Peoples (elves, men and dwarves) outside the main gate of Mordor.

Part of the Middle Earth series including Gondor "The Siege of Minas Tirith" (available separately).

Sauron is a simulation of the greatest battle of the Second Age of Middle Earth. After the defeat of Morgoth, at the end of the First Age, Sauron had inherited the position of Dark Lord and sought to subjugate the entirety of Middle Earth. A formidable mage, Sauron forged the One Ring, within which he stored much of his power and also controlled many of his minions. He was also a being of great persuasive powers and so was able to influence men to his side.

Toward the end of the Second Age, he sought to capture Middle Earth from his stronghold Barad-dur in Mordor. In doing so, he brought down the wrath of Elendil, the King of Amor, and Gilgalad, the last High Elven King. The two, forging the Last Alliance, assembled the greatest host seen in Middle Earth since the end of the First Age and sought to defeat the evil tremendous victory by the Alliance led to the seven-year siege of Barad-dur: a siege that ended in Sauron's losing the Ring during a duel in which both Elendil and Gilgalad were killed.
