"Five Magics" was inspired by the 1980 fantasy novel "Master of the Five Magics" by Lyndon Hardy, although the five magics listed in the song's lyrics a bit differ to those in the book. The five magics in the book are listed as Alchemy, Sorcery, Wizardry, Thaumaturgy and Magic. The song also refers to a Magic ritual and some storyline described in the book. This is the only Megadeth song that's truly fantasy-oriented.
Bestow upon me knowledge, wizard all knowing, all wise
I want to rule this kingdom, make sweet the breeze that was defiled
Dethrone the evil prince's iron fists in velvet gloves of sin
Parade the gray robed monks vestal virgins, wheel the wyvern's in
