Mirkwood was added to the MMORPG "" in the expansion pack entitled "Siege of Mirkwood", released on 1 December 2009, and depicting the southern area of Mirkwood and Dol Guldur. The storyline depicts a small Elven assault upon the fortress of Dol Guldur (not to be confused with the subsequent Siege of Dol Guldur, led by Lady Galadriel herself). Making a bold strike deep into enemy territory, the Elves of Lothlorien then prepare to regroup and quickly move back to the west shore of Anduin before the Enemy can retaliate in force. While most participants are unaware of the true purpose of the assault, it is eventually revealed to be a ploy to draw Sauron's attention away from Lothlorien and allow the Fellowship to safely depart it and travel down the river Anduin.
