Disregard my comment above, on how I talked about how Nakai was a pipe dream for an DLC Lord, because here comes the newest DLC, where the ultimate Imperial hunter-general will face down against the big ol' croc himself:
Total War: WARHAMMER 2 - The Hunter & The Beast Trailer - YouTubeSo Markus Wulfhart will be the DLC Legendary Lord for the Empire, and will be the only Imperial character/faction playable on the Vortex map (the Warhammer 2 base map). His special mechanic is similar to the Spanish mechanic in Total War Medieval 2: Kingdoms, where you have to keep expanding in order to unlock reinforcement from "back home", as it were. He's essentially founding an Imperial colony in Lustria, which is a bit weird for his fluff (he was mostly written to fight guerilla wars with the Beastmen back in the Empire), but oh well!
Nakai, conversely, is the first instance we have in Warhammer Total War of a good-aligned Horde faction! His horde is a bit different, in that you only unlock units with Nakai's own army, and then the other armies have other things to build and research. He is going to have to toss all those disgusting humans off the continent to keep his allies and armies happy.
Additionally, we're actually getting Gor-Rok as an FLC Lord this time!
Empire are getting Archers, Huntsmen and War Wagons (with three variations of the War Wagons, including a Helblaster Volley Gun Regiment of Reknown variant!). They are also getting a Huntsman-General generic Lord class, which I find a tad weird, but ok.
Lizardmen are getting Sacred Kroxigors (I think?) who are basically Kroxigors with magitech boxing gloves, Razordon Hunting Packs, and.... THE DREAD SAURIAN(!!). Holee crap. They are also getting Ancient Kroxigors as a generic Lord class. Again: a bit weird, but oh well.
Oh, and back home the Old World (Mortal Empires only) the Empire is getting reworked! You can now, actually, SUMMON THE ELECTOR COUNTS!
