Wars of the Firstborn is a modification based on the discontinued Ridder Clan Mod for The Lord of the Rings: The Battle for Middle-Earth II and for The Lord of the Rings: The Battle for Middle-Earth II - The Rise of the Witch-King expansion, which focuses on bringing to life as much of the Elven world from Tolkien’s epic as possible.
These are Pictures from the RC Mod that you can use as desktop background/wallpaper.
Do all of the elven and dwarven logos mean that there will be new units for said factions?
There may be some new units/heroes for those factions, but the icons generally mean where the factions are located.
RC & Beasts are everywhere so they are on the side. Acosa and Vandas are in the corner because they are not on the continent of Middle-Earth.
Aren't there dwarves in Ered Luin?
