The Sons of the Storm is a kind of artists' collective connected with Blizzard -- they're responsible for the majority of the concept and game art coming out of Blizzard, from the Warcraft, Starcraft, and Diablo series. They count Samwise Didier and Chris Metzen in their ranks, along with many of Blizzard's most popular artists. And apparently their ranks are growing -- on their latest website update, they have posted a new group picture, along with a mysterious "eighth son" that they say they will introduce sometime later, possibly months after BlizzCon. From left on the picture above, you can see Samwise Dider, Chris Metzen, René Koiter, Travis Thammer, Glenn Rane, Peter Lee, Mark Gibbons, and the Eighth Son, who a commenter over at Blizzplanet speculates may be Wei Wang.
Speaking of BlizzCon, the Sons site also says that all of the seven current sons will be signing at the convention, so be sure to bring your TCG cards, Warcraft novels, art books and anything else these guys may have worked on. We're sure there'll be a line, but if you're willing to brave the wait, you might get to meet some of the most creative minds behind Blizzard's beloved universes.
