  • This theme is based on Dmitri Shostakovich's Symphony No. 5.
  • "Iron blue" is defined as "any of various light-resistant and heat-resistant, semitransparent blue pigments of powerful tinctorial strength, used chiefly in permanent industrial finishes",[1] which likely refers to the machinery the player faces in The Munitions Factory, the stage where the theme first appeared. The word "intention" probably refers to the possessed machines, which are now "alive" and have will.
    • "Iron blue" is also known as "Prussian blue", which is a German term, the same country where the the factory is located.
