Was it Warchief, High Overlord, Overlord, High Warlord, Warlord, General and so on? Im just wondering cuz i visited the horde embassy in Dornogal and found Overlord Geyarah. Does she outrank a High Warlord? I think so but only cuz i knew High Overlord Varok Saurfang and he definitely should have outranked a High Warlord.
Its a bit weird with npc ranks imo. Alliance soldiers also have titles often that arent even within the 14 ranks like for example High Commander.
