On the theme of the 4th century Middle-earth, several mods have already been released. Tolkien himself said that there will be centuries after the fourth. What will happen if Iluvatar left this moment, but the magic remains ....
By the 5th century of Middle-earth in the vastness of Mordor (at this moment it is called the Land of Shadow)
Trolls dominated the region. Repeatedly, Ludi from Gondor, Harad and the Rune wastelands tried to master these lands. But for one reason or another, all of their communities fell or fell for unprecedented reasons. At the end of the 4th Age, during the Great Goblin Plague, people left the Mordor region. Since that time, Trolls and other evil spirits began to dominate there.
