Inazuma means lightning as far as I know, and so does the kanji on the picture. So, the artist offered Japanese style artwork that I really loved, so I got one slot. The lightning theme come from my work for the rpg Legends of the Five rings and my avatar in it, a shugenja (priest of the elements) devoted to Thunder (which is storm, lightning and heroism), which due to my work as my playtester for the game became an official character in the game. So this picture is a bit of mix of the two.
