Void elf or Kul’Tiran - you have instace where Kul’Tiran sea priest started to trasform to tetackle ‘humans’.
I remember forsake being from cult of Forgotten shadow which started with humans researching dark magic orc necrolytes practiced.
It’s the Legion expansion that threw Natalie Selie to some void stuff, but I’d argue that OG Forsaken Shadow priest was more related with typical necromancy stuff rather tha void and tentacles.
yeah you should also double down on the void go full Void Cult Priest and worship a bunch of dead hantai gods then again the herald did say the old gods are as numerous as the stars so i guess you can find a new old god to worship on some other star
