Guild Wars 2 starting July 1st, meaning that we've got a month of what will no doubt be teasers, hints, and taunts. That image above is a teaser. If you stare deeply enough, you may be able to uncover its mysteries. For within its depths lie... well... who knows?
No, seriously, we don't know either. It could be anything. Speculation has already begun, but that first image is all we have to go on for certain right now, and that means... what? Take a gander at a larger version of the image just past the break and start your speculation engines. Or just wait a month if that's your speed.
