Nightwish
In the beginning, Holopainen mainly wrote about mythological and fantasy themes, and often used references to "metaphysics and nature". Fantasy novels especially are a big influence on Nightwish's lyrics. Songs such as "Wishmaster," "Elvenpath," and "Wanderlust" make fairly clear references to fantasy novels, in this case the "Dragonlance" series and J. R. R. Tolkien's "The Lord of the Rings". "FantasMic" from "Wishmaster" is a direct tribute to Walt Disney and Disney animated films, which Holopainen has said are among his influences. "Dark Passion Play" featured the return to the fantasy theme with songs such as "Sahara", "Whoever Brings the Night" and "7 Days to the Wolves", which is loosely based on Stephen King's novel "", the fifth book in the Dark Tower series. The song "The Poet and the Pendulum's" first section is called "The White Lands of Empathica", which is a reference to in the Dark Tower series.
