Short answers, pulled from the story.
Michael Moorcock is an English writer born on the 18th of December 1939 in Mitcham, Surrey. He is best known for his novels about Elric of Melniboné, which were a seminal influence on fantasy fiction in the 1960s and 1970s, and for editing the science fiction magazine New Worlds from May 1964 to March 1971 and again from 1976 to 1996.
New Worlds was a British science fiction magazine that Moorcock edited from 1964 to 1971, during which it became central to the science fiction "New Wave" movement. It was controversial for publishing experimental literary fiction, most notably Norman Spinrad's Bug Jack Barron as a serial in 1969, which prompted members of Parliament to condemn the Arts Council of Great Britain for funding the magazine.
The Eternal Champion is a figure who recurs across alternate universes in multiple identities throughout Moorcock's fiction, navigating the fundamental polarity between Law and Chaos in a cosmology Moorcock calls the Multiverse. The concept links the Elric books, the Hawkmoon novels, the Corum series, and many other works into a single interconnected oeuvre.
Moorcock won the 1967 Nebula Award for the novella Behold the Man and the 1977 Guardian Fiction Prize for The Condition of Muzak. Gloriana won both the John W. Campbell Memorial Award and the World Fantasy Award for Best Novel in 1979. He was named the Science Fiction and Fantasy Writers of America's 25th Grand Master in 2008 and was listed by The Times as one of the fifty best British novelists since 1945.
Moorcock collaborated with Hawkwind on several projects including the album Warrior on the Edge of Time, for which he earned a gold disc, and he wrote the lyrics to "Sonic Attack." He wrote three album tracks for Blue Öyster Cult, including "Black Blade" and "Veteran of the Psychic Wars." His own project, Michael Moorcock and The Deep Fix, released its debut album New Worlds Fair in 1975 and the album Live at the Terminal Cafe on the 11th of October 2019.
Moorcock began contributing to a magazine he called Outlaw's Own from 1950, while still at school. By 1957, at the age of seventeen, he was editor of the national juvenile weekly Tarzan Adventures, which had already published at least a dozen of his own "Sojan the Swordsman" stories. At eighteen he wrote the allegorical fantasy novel The Golden Barge, though it was not published until 1980.
