Last week we brought you the fly-through trailer for a zone on the Elyos side of things, from the upcoming Aion expansion, Assault on Balaurea. This week NCSoft is back with another trailer along those same lines. This time, however, it is showing off a predominently Asmodian zone, Gelkmaros. So, for those of you who like the arguably darker and lesser-played side of things, you might want to hit the jump to check out this week's fly-through video.

Aion: Assault on Balaurea releases in just one week, on September 7, 2010. It's a pretty sweet MMO, from my time with it, at least. In a way I want to go back, but I don't have the heart to give up WoW....
