The Mandrake Project

Part of the original announcement for the album explained that it would be a narrative concept album accompanied by a 12-issue comic book series published by Z2 Comics. The story was written by Dickinson, scripted for the comics by Tony Lee and illustrated by Staz Johnson. The announcement stated that the full story would be "a dark, adult story of power, abuse and a struggle for identity, set against the backdrop of scientific and occult genius."^[15] Dickinson would later say the original intent was only the comic, but he grew ambitious and added a related album. Conception of the album begun in 2014 under the title If Eternity Should Fail, with Dickinson writing songs alongside producer Roy Z. Once Iron Maiden bassist and main composer Steve Harris heard the demo for the planned title track "If Eternity Should Fail", he asked Dickinson to bring it to the band's new album, The Book of Souls. After doing so, Dickinson decided he would not feature the song as the album's centrepiece,^[16] eventually reworking it into "Eternity Has Failed", featuring different music and slightly different lyrics.^[17] Dickinson would leave the project aside for seven years given he underwent a cancer treatment and toured with Iron Maiden, reviving it during the COVID-19 pandemic, renaming it The Mandrake Project and deciding to keep a few of the already composed songs like "Shadows of the Gods" mostly unchanged. One of the tracks, "Sonata (Immortal Beloved)", was even older than the initial concept, emerging from a short instrumental based on Moonlight Sonata that Z recorded after watching Immortal Beloved, to which Dickinson quickly improvised some lyrics. During production, Dickinson's wife Leana found the demo, liked it and encouraged him to include the song in the album.^[16]

The first single released to promote The Mandrake Project was "Afterglow of Ragnarok" on 30 November 2023. The song was released digitally and as a 7" vinyl single in a gatefold sleeve, which included an 8-page prequel comic inside. The B-side of the single featured Dickinson's original solo demo of "If Eternity Should Fail".^[14]

"Rain on the Graves" was the second single from the album, released on 25 January by BMG Records and accompanied by a music video similar to the first single. The song features a guitar riff, keyboard sections and a narrative vocal performance. The song was inspired by Dickinson's visit to the grave of Romantic poet William Wordsworth in the Lake District.^[18]

The album was released in various configurations on both CD and vinyl LP, as well as digitally on all major streaming and download platforms. The CD version had two main configurations on release. The standard CD came in a three-panel full-color cardboard sleeve with a 20-page booklet inside the first panel, containing lyrics and production details. A limited edition version of this included a lenticular cover, which is loose and not glued to the front of the actual case. This edition was exclusive to Walmart in the US and HMV in the UK.^[19]

A deluxe limited edition of the CD came in a 7" hardback book which contained a preview of the album's companion comic book series. The CD was in a cardboard pouch inside the book, and the book came in a slipcase. The lyrics booklet from the standard CD was also included. The slipcase had the same cover art as the standard CD, while the book had exclusive cover art by comic book artist Bill Sienkiewicz. Some copies pre-ordered from Dickinson's official online store included a signed photo inside the book. The vinyl LP version came on standard black vinyl, with a limited edition version on blue vinyl and including an exclusive 'M' stencil. Copies of the black vinyl pre-ordered from Dickinson's official online store came with a signed art card.^[20]
