Explaining the album title, which is also the title of the album's fourth track, Ian said: "The meaning, to me, for this title is that everybody can be a king. Everybody can have control over their own lives, control over their destiny, just by growing up and becoming a responsible human being. I'm not necessarily saying that being a "king" is being the boss in your relationship, or any relationship for that matter. A king of yourself is what I mean. Taking responsibility and ownership for your own shit is basically what it means to me." Ian, who writes the band's lyrics, said he tried to incorporate different structural ideas for the lyrics to those featured on previous albums, crediting author
David Mitchell as an influence. Ian has said that "Breathing Lightning" is lyrically influenced by author
Stephen King: "If I had to pick one thing that I love the most from him, it would be
The Dark Tower books [...] The character
Roland, it's just something that stays with me a lot, this character from those books. So I kind of re-entered that world again. 'Cause I wrote "Lone Justice" way back when, on the
Spreading The Disease record, which was based on that character, and I decided to re-visit it, because, metaphorically, there's so many things you could use it for[...]I'm kind of weaving in and out of reality and fantasy in that song. And 'Breathing Lightning', of course, is a metaphor for shooting." According to Benante, "Evil Twin" was inspired by events like the
2015 attack on the offices and staff of the French satirical publication
Charlie Hebdo and various other mass shootings. Ian added that it was about by the actions of people "who feel they have become judge, jury and executioner over their fellow man", calling this mindset the "evil twin" of humanity. Ian has described "Blood Eagle Wings" as the "centerpiece" of the album, and admitted having difficulty with writing the lyrics. Lyrically, the track concerns "Any great city, whether it's
London,
Rome,
Paris,
New York City,
Los Angeles – these cities are alive because of how many people were killed to make them what they are. How much blood was spilled over time." ==Release and reception==
