Tide of Hellkrusha

The Tide of Hellkrusha was an Imperial campaign carried out by the Seraphim of the Abyss] Space Marine Chapter in the defence of their Chapter homeworld of Boletaria against the Orks of WAAAGH! Hellkrusha.

History
After the successful hunt for the treasonous Radfael of the Fallen, the Seraphim of the Gryphon returned to their homeworld to find an Ork WAAAGH! ravaging through the sub-sector. Under the leadership of a fearsome Warboss by the name of Krokugg Hellkrusha, a xeno so frightening that rumors were abound that he might have been a vestige of the dead Orks of Ullanor. Hurrying to protect Boletaria and its sister planets, the knights of the Chapter found Hellkrusha to be a true foe, besting many of their attempts to thwart his path of destruction. But when the First Company, the Deathwing, and the Chapter Master assaulted Hellkrusha in a climatic duel, eventually proving the superior, Grand Master Droyn Sariel sustained many wounds before slaying the Warboss with a power fist sent into the Ork's face.
