Middle Earth
The stories set in Middle Earth take place across three different time periods known as Days Before Days, Years of the Trees, and Years of the Sun. Arda
Marred takes place on Middle Earth during the Third Age at the end of the Watchful piece. The third age takes place during one of the four sub-divided ages
in the Years of the Sun. During this time in Middle Earth, Sauron has returned to Dol Guldur where evil creatures had already begun troubling those who lived
there. It was not long after the watchful peace that Uruks from Mordor began invading Ithilien and took Osgiliath. From that point, Gondor would remain under
constant threat of invasion.
