Tarnis is a Civilised World controlled by the Imperium of Mankind. It was the ancestral home of the Imperial Knights' House Drakkus, thus also making it a Knight World. Tarnis came under attack by an alliance of a well-supplied Khornate warband and Orks of the Bad Moonz Klan under the command of Boss Nekkruncha.

A force of Dark Angels under the command of Master Tigraine on board the Strike Cruiser Fist of Caliban answered the call for aid by House Drakkus and entered the conflict alongside the last remnant of that Knight House, the Freeblade Vortigan.

The Dark Angels did not realise that the Forces of Chaos had struck at Tarnis as it was the location where they planned to enact a Chaos ritual that would summon the Bloodthirster Felfurion from the Warp into realspace.
