Fist of Crota
The Guardian lands in The Blast, where a large battle rages between Fallen and Hive. A Skiff drops off Fallen troops, running into the fray. A piercing, inhuman shriek is heard, and a large Wizard appears behind the group of Hive. With another shrill cry, Omnigul, Will of Crota, summons more Hive enemies, including Thrall, Knights and Cursed Thrall.
The Guardian defeats the enemies, and Omnigul disappears.
Upon entering the Refinery, a loud metal grinding sound is heard around the corner. The Guardian stops to investigate. Three Acolytes are kneeling in a circle, a green cloud swirling above them. The noise intensifies, and the cloud grows, turning into a large Knight with a Cleaver. The Guardian kills the Knight and the worshipping Acolytes. The Blade of Crota falls to the floor, and the Guardian picks it up, using the weapon of Darkness against Thrall, Acolytes and Knights in the adjoining room. The Guardian continues into the winding tunnels in The Grottos.
Arriving in the waterlogged caves, the Guardian comes across a much larger cloud of Darkness. Upon inspecting it, A Dark Burden weighs heavily upon the Guardian's back, limiting their movements. With a roar, Sardon, the Fist of Crota appears. Fighting despite their burden, the Guardian eventually kills Sardon, and the haze is lifted.
