The Binding of Fenris is a potentially lost work written by Palatine Bedras. The book is an autobiographical account covering the discovery and subjugation of the World Eater, Fenris. Written approximately seventy years after the events described within, The Binding of Fenris saw only limited replication in the millennia to come and never achieved widespread recognition. In 2401 ABA, the book was declared heretical by the Bedran Cult and most of the existing copies were destroyed. The only copy of the book known to have escaped perdition is the one owned by Emperor A222, who kept it in his private library on Nova Prime. The current status of this copy is unknown.
The nature and contents of The Binding of Fenris have been referenced in other works dating to the era. Many of these works have likewise been censored and had the references written out of them in later editions. Most of the information known about the book come from early editions of these other works, themselves a rarity.
The Binding of Fenris was a first-hand treatise detailing the uncovering, awakening, rampage and taming of the World Eater. The account was noticeably bereft of the artistry and metaphors common in other Bedran religious texts, instead presenting its contents in a straightforward and factual manner. The majority of the book was dedicated to conversations between Bedras and Fenris during and after the binding, written verbatim. In it, Bedras speaks at length about his own past and personal philosophy - including his mortal life in another reality - and the World Eater does likewise. The dialogue between the two deities contained several revelations about not just the history of the Bedran Marches, but of the galaxy itself.
The book came to the attention of the Bedran Cult after a copy was discovered during renovations on the Archbasilica on Ur-Nammu. According to a confessional written by one of the priests who partook in the review later broke his vow of silence, the revelations made by Bedras did prove controversial upon the book's analysis. Yet ultimately it was the words of Fenris, not Bedras, that resulted in the book's condemnation. The reaction was so extreme that a vocal minority of the priesthood called for the destruction of the World Eater's dormant body on Atreides. These extremists were silenced and a public ban was placed on The Binding of Fenris.
