The cover art, featuring a landscape divided into night, summer and winter, was meant to depict nature. However, Tony explained that the cover was not supposed to feature too much symbolism, except for the footprints leading away from the campfire. He explained:
That thing is like representing a snippet of your life that really makes you go one way or the other. Either way can be the good way, not the bad way necessarily. The album is one of those things that's a bit different, a more difficult album.... make it go one way or the other.
The title of the album was at first supposed to be longer, but Kakko's then girlfriend suggested "silence" and he reflected on how important silence was for him:
[silence] is a creating force because when you're on the road for half a year or something like that I can't make new music at all so I need something like a month or two to get my head working again. So that's my "silence" it seems.
The second track "Weballergy" is considered by Kakko to be a sequel to Ecliptica's "Blank File", as both of them cover the theme of Internet privacy.
"The Power of One" is the longest Sonata Arctica song to date, at a length of 10:40, not including an extra minute of silence in the end.
