Far as I know, Mayong was in Mistmoore castle even after the servers went live (after beta). It was only after he had wacky aggro problems that they removed him. I heard he was nasty and would just swoop in and wipe everyone out near the zone line...and then wouldn't return to his spawn point. So he would promptly put the smack down on everyone when they came back to get corpses... yeah...he rules.
