Soo....let me see if I've got the plot right.
Lorien has been assalted twice, and now sends out an envoy to Thranduil asking for aid. This envoy is captured by a party of Easterlings and orcs and is subsequently rescued by a scouting party from Mirkwood. Meanwhile, during the 3rd attack on Lorien, a elite party of Uruk-Hai and Easterlings are sent to kill Galadriel and destroy the defenses that Nenya provides. They must get past a very small force protecting the Lord and Lady of the Golden Wood, who are fighting vailently against the incursion of orcs and Easterlings. At this point, its a race against time for the combined party of Mirkwood and Lorien elves to get back to Caras Galadhon and stop the baddie elites from taking the Golden Wood and killing Galadriel.
Right?
Ohh, this sounds fun. And as to the theme music...The Empire March, huh? That might work. I'll give it all some thought.
