If you watch the movie you'll see a Troll escaped plus the goblins were still in the mountains and on top of that orc's were a cross beween goblin's and elve's the woodland elve's are still in mirkwood convintly close to dol gundor so evil will return and I think that their base will be Rivendell seeing as all the elves left and t's just sitting there with a perfect position for war first of all it's in the mountain's so they have the high ground. second the elve's left their weapon's there. third there seems to be a secret entrence leading to dol gundor seeing as Elrond got there so fast on foot with heavy armour on. fourth there is a lake at the bottom with plenty of fish s they'll never go hungrey.
