Nine-Piece Masked Collective Arcus Emerges Online Claiming Links to Sleep Token
A mystery group has surfaced with horror-inspired music videos, an interactive viral puzzle site, and claims regarding a Sleep Token co-creator.
The Debut and Video Releases
A new masked musical project named Arcus began its public campaign on Sept. 18 after uploading an introductory video to YouTube titled "Introducing: Arcus." The clip features horror elements—including figures in masks, a cave-type dwelling, and a church—accompanied by text that reads: "From the co-creator of Sleep Token comes a chance to bear witness. Have you seen them?" The video ends with a prompt to "Join the assembly" and directs viewers to the website whatisarcus.com.
Arcus has since released two music videos on YouTube for tracks titled "Death" and "Rebirth." Both songs feature male and female vocalists:
- "Death": Atmospheric sound driven by a pop beat.
- "Rebirth": Accentuated by heavy metal riffs.
On Spotify, credits for both tracks list The Arcus Collective as lyricist, composer, and producer, with Diego Fernandez also credited as a producer.
Arcus Band Lineup
YouTube descriptions confirm the project features nine total musicians, though most identities remain undisclosed.
- Soma Leith
- Obsidian
- Istarion
- Eupheryx
Five remaining roles in the band are designated with three question marks ("???").
Interactive Website Details
The home page of whatisarcus.com displays a dark background with a glowing logo and text reading "Arcus Awakens." Clicking the entry button leads users into a interactive virtual room containing a desk, file cabinets, an evidence board, and a staticky television.
Sleep Token's Response Statement
On Oct. 18, Sleep Token published a statement on social media addressing unverified association claims:
"A word, for the sake of clarity. Sleep Token has no affiliation with any outside musical project that invokes this name, nor with anyone who uses it to promote one. Such claims are not made with our blessing and are not endorsed by Sleep Token. What is ours is here and here alone."
