[7][1] Trym Torson, of Emperor and Enslaved, played drums on the majority of the album, excluding the tracks "Floods," "Acolytes," and "Empyrean.

Abigail Williams released the deluxe edition of In the Shadow of a Thousand Suns on January 12, 2010, which included a second disc featuring four new songs, one unreleased demo of "Floods," and the music video for "Into the Ashes.

The EP consisted of "I Am (God)," "In Death Comes the Great Silence," the instrumental "Waiting for the Rain," "Infernal Divide," and "Floods.

"[13] The demo version of "Floods" was included on the new release because, as Sorceron stated, "it captures the vibe of the song better than the album track; perhaps due to the work of original drummer Zack Gibson.

"[11] The music video for "Into the Ashes" intercuts a brief tale of a girl and a man with the band performing the song in a catacomb setting.

The dark ambiance and characters' period dress creates a gothic feel over the entire video, although the band members remain in contemporary apparel, including T-shirts and jeans.

The song jumps into its heavy, fast-tempo riffs, and the video repeatedly cuts between shots of the guitarists and drummer while the girl slowly walks back into the shadows.

The video begins focusing on the band members' performances, cutting between guitars, drums, keyboards, and singing, infrequently using strobing lights to emphasize the double-bass rhythm.

The band was almost consistently lighted from the "front" (behind the camera), with varying degrees of brightness, at times revealing the subterranean backdrop.
