What I can find of Ogrezonia is from a Jewelcrafting daily quest in Stormwind and Orgimmar. Here’s the Wowhead quest info for Alliance and Horde.
Ogrezonians in the Mood (Alliance)
Ogrezonians in the Mood (Horde)
Since the quest text appears to be the same for both factions, I’ll copy and paste it here:
“I was supposed to receive a shipment of jasper from Azeroth Express, but I just heard their ship crashed into some tiny island called Ogrezonia. I worry about the crew, as the giant female ogres on the island are rumored to perform horrible rituals on men who happen upon their island. My work must go on, though, and we need those gems. I’ve heard great things about your skill as a jewelcrafter - could you deliver three jagged jaspers by the end of the day?”
Seems to be all I can find in-game regarding it. It may have just been created for humorous flavor text, so I’m unsure if Ogrezonia would ever be utilized at all in-game.
I also expect that if we get Ogres to be playable, female Ogres would just pop up out of nowhere and nothing really is said about where they have been. A few playable races have done this before, along with a few candidates for future allied races like the Gilblins, so I’d be surprised if Ogrezonia is referenced at all for female Ogres if they were ever put in the game.
