Folks are saying this has been around since release, but I've never seen this before, either-- Serevarno found a face in the landscape of Searing Gorge. You can really only see it on the minimap, and while it is pretty messy, it's too clean to have happened by chance. The image almost looks like that "Andre the Giant has a posse" picture, doesn't it?
Bornakk jokes that the Titans left their face there before heading off to another world, but while that's probably not the case (Titans aren't that grubby), it is interesting that he should say the Titans leave their images sitting around-- we've already seen Titan statues appear in the videos for Northrend, and it's been confirmed there's a Titan instance up there. Leaving their images sitting around is definitely something they are wont to do.
But of course it's doubtful this has anything to do with the lore-- at most, it's just a developer hiding an Easter Egg, and at least, it's just a coincidence. Still neat, though.
