The female character's design in the cover art seems to be inspired by the Power Chord skin from the aforementioned game, while the male character's design is based off of Gammer's real life look.
The word "The" doesn't mean it occurs mostly in the "T" section; rather, it is excluded so that the next word after the word "The" (e.g.: "The Alchemist's Nightmare") will occur in that specific letter (e.g: "A").
