Third Age: Reforged is a mod for Medieval II Total War, that aims to overhaul the multiplayer aspect of the Third Age Legacy, by thoroughly rebalancing the units and factions while also implementing tons of new content, maps, units, etc. (NOTE: campaign is still in development)
Damn those guys look really bad@
Any background about these units? Where are they from I wonder. If they're Elven, it seems like an Avari sort of unit.
They're a reskin for the Staff Masters, but other than that I'm not sure they have a particular backstory.
