Shit, ok we'll need to get a hold of that Bishop, and maybe lean on some of our more big picture type friends to figure out how to make this work because we need infrastructure experts if we're going to rule frigging azeroth humans.
It's one of those things when it comes to being da boss. So to follow what past conquerors do they would seek to get the locals to collaborate especially the institutions they take over. Some things can be relatively simple to fulfill as the new overlords to their subjects. Get the taxes and harvests done on time, infrastructure improvement etc. as long as they fulfill their own obligations namely protecting them.
Grok is quite good at making sure they're protected right now. The resistance of his predecessor has been beaten and the matter of orc raiders too is taken care of since he set out to make sure they stop raiding them.
It does come to something like a survey to the locals if they like the current overlord in charge which is something definitely in conflict to say.
On one hand they're ruled by outsiders. Orcs especially even if it's one led by an orc who can use the light. On the other other hand the predicament they're in is because their past king tried to join the winning side of the time and betray the alliance which led to their predicament with Alteraci joining the syndicate to start a resistance and continue methods that alienate horde and the alliance.
I'll assume since Grok went in and beat them up their attitude is that they're too weary to care and just want some peace and stability for the old ones. The young ones might be too belligerent but that's the folly of youth until Grok or someone else straightens them out to tough it out until things change later for better or worse.
So of course there's the Bishop as the instant local to refer to besides random defeated Alteraci nobles who probably hates what's happening but are resigned to it all.
Danrothan or members of the Alliance could send help because they need Alterac's mines set up for the war effort.
The black dragons can also be a balancing factor.
Feldad too could send help especially when his son has a place to stay in more permanently.
