The royals in chardok respawn really quickly. I forget the precise timer, but it's like 1-2 hours. Also they do not have MOTM, so you can trigger a pick for an instant new set of spawns. Good luck
The AOC on Agnarr is probably for Chardok B. There is not one in any era for base Chardok as far as I know. I would love one to be available because instanced content being available (even once a week) lets people have fun without the insane toxic competition over every last scrap in the open world. That said it's probably not happening because the servers can barely sustain the currently load and I think early era DZs are a significant strain because of the way they were coded.
Chardok does not have an AoC instance because there are no events in the zone that met our criteria for raids. According to data, the royals respawn every 120 minutes.
Correct that he does not spawn an instance - but he is there in the tunnel leading to the zone out. He answers hails and acts like he's spawning you something but nothing happens.
He's the AoC for ChardokB (Chardok: The Halls of Betrayal) I tested it out on the Test server and it seemed to work OK, though I bypassed the 6 person restriction by spawning the DZ manually.
I think Korucust is the one raid encounter of the zone https://everquest.allakhazam.com/db/npc.html?id=12529
The guards in Korocust's room are also deceptively chonky, made the mistake of pulling some of them when doing hunters and was real confused why they were so much harder than everything else in the zone.
