For some reason or another:
• Whatever being feels like it who looks at this entry has to post this meme and their current wallpaper on their LiveJournal.
• Explain in five sentences why you're using that wallpaper!
• Don't change your wallpaper before doing this! The point is to see what you had on!
It is a bit...exaggerated, admittedly. Fire imps like Landslantern there are only about the size of a housecat.
As for why? Dwarf Fortress. Fullstop.
