[HACK NEEDED]
Well basically if u fly east north east from The Tempest Keep ocasionally using XYZ hack to bypass invisible walls u reach a large square of land. If you land on this and check your map u will see ur in the zone just north of epl. You can get to ghostlands from here too. I don't have cataclysm so i got dismounted the second i flew into ghostlands :/ . I think its because ghostlands and such are on the outlands map. it also explains why the rest of azeroth isnt actually there even if u fly over it. Hope this helps =)

Flying directly south of this will bring u to azuremyst islands although i wouldnt reccomend it at as u just get dismounted and fall to your death :/ This can also be achived by flying directly east of the dark portal and using XYZ again to bypass barriers.
If you fly east of ghostlands (alll the way now to the edge of the zone) you get to this strange forest thats all lit up and considered part of the Twisting Nether. Theres also a version of Zul'aman there, kinda like an uninstanced version
