The named track
Warhammer Community names Ascent of the Arkifane in its official trailer article. The release trailer’s English captions also display the track and composer credit. Together they verify the name without relying on a listener’s guess about the music style.
The credit appears in the promotional release reveal. That makes the trailer an authorized preview of the announced contribution. It is not a separate soundtrack album release or a complete published tracklist.
The final boss connection
Auroch Digital’s FAQ describes Gordon’s contribution for the final boss battle. The official Steam launch announcement confirms that scope. Vashtorr is the central antagonist revealed in the associated official story material.
The boss guide records the confirmed encounter context. A soundtrack credit does not show how the battle resolves or how to beat it. The ending overview keeps those story questions outside the verified reveal.
How the collaboration was announced
Wargamer reports the track and its association with Vashtorr. GamesRadar’s event recap also identifies Gordon’s collaboration alongside the October release announcement. Those reports corroborate the disclosed contribution rather than supplying additional uncredited tracks.
The official release trailer was also uploaded by the publisher. Reuploads of the same promotional video are repeated publications of one reveal. They should not be counted as independent recordings of the final boss fight.
The soundtrack scope that is verified
The supported statement is a named contribution for the final encounter. The collected material does not supply every music credit, an album date or an authorized download catalogue. No complete-soundtrack authorship claim or copied lyrics are added to that narrower answer.
