I’m not married to it, I just can’t think of any other named Forsaken that’s been around as long as he has.
Gunther Arcanus!
Maybe the Forsaken can go full anarchy. 
I’m partial to a council though.
Desolate Council:
1- Deathstalker Commander Belmont
2 - Gunther Arcanus
3 -
4 -
5 -
6 -
7 -
8 -
9 -
10 -
So on and so forth
22 - Michael and/or Patrick Garrett?!?! (Bat Handler and Innkeeper)
Go!
But alliance loves human potential!

He’d be fine.
I may be in the minority wanting Lillian Voss to serve as well.
What about High Executor Anselm? I think he’s still kicking.
Not sure about the Dark Rangers - any of them loyal to the Forsaken and not Sylvanas?
He doesn’t even have a whip. How can he call himself a Belmont if he doesn’t have a whip?
There’s arguments for and against the preservation of the Lordaeronian Monarchy, but a major problem they’re going to have going forward is…the line is ended. Ain’t coming back. You might say, “but Calia can just be queen forever!” and I would say “How’d that work out with your last queen?”
I have nothing against Calia, but there has got to be turnover of some kind in an effective government. New ideas, and all that. After giving it thought, I think the best thing for the Forsaken leadership is, in fact, a strong military leader at this time. Not to wage war, but to manage de-escalation, which is the responsibility of the military as well (no matter how rarely that ever goes into practice).
Maybe it’s not Belmont, but it’s certainly one of his like. Leadership and command, responsibility to those under that command, but not such an ego that would supersede the input of advisors. It would also be a fine chance for Blizzard to build a character up from very little, as opposed to taking yet another “hero” character and giving them a desk job that they get bored with.
Dark Ranger Velonara can represent the dark rangers.
What about our boy Helcular?
The point is, there are so many great Forsaken characters already.
Bringing in an Alliance NPC to take over is probably the stupidest thing that Blizzard has ever done to the world of warcraft.
Except maybe for that time travel mirror universe nonsense.
Helcular is a must!

I don’t know how it would work with the Forsaken, but Calia does actually have a daughter.

As long as they and any other dark ranger asked to serve had nothing to do with killing the last council.
Dude I loved seeing him slaughter things during the Legion prepatch.
I don’t think it ever mentioned who killed them specifically. But they could just say it was the ones that left with her.
Calia needs to go the way of Med’an.
I don’t know how that character made it out of early drafts.
Time to bring out the national razor for our good little monarch
Can I also point out how Calia did a complete 180 between Legion and BFA?
In Legion she tells you she has no interest in Lordaeron, those days are behind her. She’s focused on helping the world and working with Alonsous Faol.
Then Sylvanas kills her and a Naaru resurrects her, and suddenly "I MUST LEAD THE FORSAKEN!"
