Дол Гулдур
There are several scenarios with smaller maps, including "The Battle of Five Armies" - based on "The Hobbit", "The Untold War" based on the battles from "The Lord of the Rings" not focused on in the novels, focusing on Dol Guldur and Lothlórien which are only covered in the appendices, and variations on the main game, including "Kin-strife" and "Gunboat" variations.
