Castle Greyscale is a huge, imposing castle located on the border of Etonia and Hyperborea. Greyscale has always held significance as a strategic objective in the power struggles of the Etonian power elite. Every war to have been fought on Etonian soil was waged with the single objective of gaining or keeping possession of Greyscale and its mysterious towers. Greyscale is also a popular sporting venue, playing host to Glasgow Rangers and the Fucking Yankees.
