Firstly we had Verbrek for that hunger games thing. And Von Kharkov was one of my favourite darklords storywise but also I really liked his total control of his domain, having learned a lot as a veteran Kargat vampire. His portrait by Stephen Fabian is one of my favourite depictions of a Darklord . Chakuna's name was probably inspired by chakana (or Inca Cross) that is suggested to represent the other two levels of existence. So I guess it follows up the Andean-inspired version of Valachan of 3rd edition but still I wonder why reinvent a domain to be similar to Verbrek and then don't include Drakov because there is already a Vlad the Impaler inspired darklord in Barovia, while being practically totally different (Strahd being a kind of an elegant recluse while Vlad is a brute who wants to be cheered or at least feared to feed his ego).
I think it's pretty obvious why Von Kharkov had to go.
