Taken from https://wow.gamepedia.com/Ogre:
Maps for the alternate Draenor feature an unnamed landmass southwest of Draenor's main continent, described at BlizzCon 2013 as a "mysterious ogre continent" from which the Gorian Empire originated and where their main seat of power was still located, with their influence having spread to Draenor's main continent over time. The existence of this continent appears to have been retconned, as Chronicle Volume 2 never makes mention of it and instead places the ogres' original seat of power in the city of Goria in the center of Draenor's main continent. However, the landmass can still be seen on in-game maps of Draenor.
- High Centurion Tormmok still mentions having campaigned on two continents.
- The original maps for Draenor also featured a large island south of Nagrand. The official Warlords of Draenor site described seafaring ogres claiming the south of Nagrand, but this plot point was removed during development.
So what do you guys think?
Is it simply a retcon and Blizz hasn't bothered to change the in-game map? Or do you think we'll see some iteration of this continent in a future expansion (perhaps 9.0 after the South Seas), albeit something different than what they originally planned? It could be that other continent that High Centurion Tormmok mentioned in passing. Maybe we'll see the "fara" Primals of Farahlon in said expansion.
