The Wheel of time or wheel of history (Kalachakra) is a concept found in several religious traditions and philosophies, notably religions of Indian origin such as Hinduism and Buddhism, which regard time as cyclical and consisting of repeating ages. Many other cultures contain belief in a similar concept: notably, the Q'ero Indians in Peru, as well as the Hopi Indians of Arizona.

The Wheel of Time or Kalachakra is a Tantric deity that is associated with Tibetan Tantric Buddhism, which encompasses all four main schools of Sakya, Nyingma, Kagyu and Gelug, and is especially important within the lesser-known Jonang tradition.

The Kalachakra tantra prophesies a world within which (religious) conflict is prevalent. A worldwide war will be waged which will see the expansion of the mystical Kingdom of Shambhala led by a messianic king.

In an interview included with the audio book editions of his novels, author Robert Jordan has stated that his bestselling fantasy series The Wheel of Time borrows the titular concept from Hindu mythology.^{[citation needed]}

Blind Guardian is a German power metal band formed in the mid-1980s in Krefeld, West Germany. They are often credited as one of the seminal and most influential bands in the power metal and speed metal subgenres. Blind Guardian is a part of the German heavy metal scene that emerged in the mid-1980s.

The band's lyrics, written by vocalist Hansi Kürsch, are inspired by the fiction of fantasy authors such as J. R. R. Tolkien, Michael Moorcock, Robert Jordan and George R. R. Martin as well as traditional legends and epics. Over the years, a running theme has developed personifying the band members as travelling bards, leading some fans to refer to the band affectionately as "The Bards".

Blind Guardian was formed in 1984 in Krefeld, Germany, by Hansi Kürsch (vocals, bass) and Andre Olbrich (guitar) under the name Lucifer's Heritage. The band first released two demos in 1985 and 1986, despite undergoing chaotic lineup changes: Markus Dörk (guitar) and Thomen Stauch (drums) were replaced by Christof Theißen and Hans-Peter Frey, respectively. Finally, in 1987, Marcus Siepen joined and Thomen came back to form the lineup which would stay consistent for the next 18 years.

Robert Jordan was the pen name of James Oliver Rigney, Jr. (October 17, 1948 – September 16, 2007) He used this pseudonym for fantasy novels, including the bestselling The Wheel of Time series for which he was best known; he also wrote historical fiction as Reagan O'Neal, a western as Jackson O'Reilly, and dance criticism as Chang Lung, and he had ghostwritten an "international thriller" that is still believed to have been written by someone else.

Jordan was born in Charleston, South Carolina. He served two tours in Vietnam (from 1968 to 1970) with the United States Army as a helicopter gunner. He was awarded the Distinguished Flying Cross with oak leaf cluster, the Bronze Star with "V" and oak leaf cluster, and two Vietnamese Gallantry Crosses with palm. After returning from Vietnam he attended The Citadel where he received an undergraduate degree in physics. After graduating he was employed by the United States Navy as a nuclear engineer. He began writing in 1977. He was a history buff and enjoyed hunting, fishing, sailing, poker, chess, pool, and pipe collecting. He described himself as a "High Church" Episcopalian and received communion more than once a week. He lived with his wife Harriet McDougal, who works as a book editor (currently with Tor Books; she was also Jordan's editor) in a house built in 1797. Responding to queries on the similarity of some of the concepts in his Wheel of Time books with Freemasonry concepts, Jordan admitted that he was a Freemason. However, "like his father and grandfather," he did not prefer to advertise, possibly because of the negative propaganda against Freemasonry. In his own words, "no man in this country should feel in danger because of his beliefs."
