A picture!

Why not. It's been a long time since I've drawn something that I liked enough to use as a desktop image. ;p (Although there were some LoL comics and such that I drew in 2012-2013 which I liked, but never posted here, and weren't desktop dimensions..)

In League of Legends, one of my favourite characters, Janna, has a skin named Tempest Janna. In Heroes of the Storm, which came out much more recently, Jaina Proudmoore has a skin based on the Tempest Regalia set in World of Warcraft, named Tempest Regalia Jaina, which I'd frequently call Tempest Jaina. Jaina was my best character in HotS too, so it's a wonderful coincidence.
