* With Märchen being Music/SoundHorizon's seventh "[[RockOpera story album]]", Revo amused himself by making use of the number seven constantly (over a hundred times, in his own words) throughout it: The album's story revolves around Märchen granting revenge to seven dead women from seven fairy tales, each associated with one of the SevenDeadlySins. One of them is "Literature/SnowWhiteAndTheSevenDwarfs". The lyrics booklet is seventy-seven pages long, and the number seven always appears in [[color:red:red]].

In the natural world, one of the origins of this significance come from the seven celestial bodies that could be seen with the naked eye, (Sun, Moon, and the planets up to Saturn[[note]]If the motion of Uranus had been noticed, the lucky number would likely be eight instead[[/note]]), that were worshiped as deities, and the days named after them were the days of the week.
