Xal’atath. Their names are even pronounced similarly.
Queen Zaltra was a nerubian queen who wanted to enslave the earthen and started a civil war in the nerubian empire. She was than banished, and rumors are that she never died and still wanders around. It’s in a lore book in the nerubian capital. She was also a harbinger, the same title that Xal’atath has.
Seems like Xal’atath didn’t randomly go to Azh-Kahet - she was returning to her old empire, wanting to take back what was once hers.
That makes no sense chronologically. Nerubians are descendents from the Aqir. The Nerubians evolved after the Titan ordering on Azeroth. Xalatath however is older than Azeroth itself. Nice theory though, but it’s not possible.
Well… more or less. She can’t really have been born that way. But Xal’atath was also Archmage Drenden. She can take other forms. She could in theory have tried her luck as a nerubian.
