Eregion is falling, the uruks have invaded the city, Gil-Galad, Elrond and Arondir, are inside captured by uruks destroying everything. Sauron in the high point of the biggest tower had killed Celebrimbor and is now turning the uruks against Adar just by talking to them. Galadriel is leading civilians outside.

Meanwhile in the forest, Adar has one of the rings of power, Nenya, his face healed from the corruption leading him an elf again. He was knelt on the earthy floor of the forest, in front of a rock, the crown of Morgoth resting on top of it.

It is when you arrive led by uruks, you leave the battlefield to convince him to stop, to release Gil-Galad, Elrond and Arondir. That they could still fight together against Sauron.
