2 interesting facts: 1) Arkhan is one of the 4 legendary lords available for tomb kings. He bro-fists VCs (diplomacy-wise), while other TKs hate the vamps (little surprise here). 2) TK campaign is about collecting all 9 books of Nagash and then winning the battle for the Black Pyramid.
I am looking forward to watching Lionheartx10's run through this campaign in 2018. Total Warhammer 2 has a number of improvements over Total Warhammer 1, but apart from the High Elves, none of the races have been of interest to me. This is no surprise, as I never liked Dark Elves, Skaven, and Lizardmen when I used to play Warhammer either, so it's great to see Tomb Kings being added so soon, especially given how good the trailer was.
