Editing Star Krakens (legacy) (section)

===End of the Heorot Crusade===
Finally, after two decades, and at great cost to his Chapter - not to mention the uncountable expense of human lives - the Grendel Homeworld was cleansed. Achab returned to his orbiting vessel, his Captain's were relieved, expecting their leader to turn them out of the dread nebula, the last of the Grendel worlds now laying deceased below them. Instead he roared onto the bridge of his cruiser, demanding the serf he had left in charge tell him the trajectory of escaping alien vessels. There had to be some, they had always escaped before, deeper into the cursed nebula, into the darker parts their auger arrays just couldn't penetrate. The vessel's commander threw himself on Achab's mercy: the alien ships had outnumbered them significantly, and although their weapons were no match for Imperial might, the vile xenos had begun using their vessels as weapons, seeking to ram their cruisers, forcing them to focus on maneuvering nimbly to avoid being sunk. In all that confusion, and with the auger arrays difficulty, they had no way to track every vessel...

Achab had the man flogged, publicly. He prepared to turn his vessels on the depths of the nebula, to plunge into it like the dagger he had used so often to tear open the thick burlap chests of the aliens on the world below, but other troubles drew his attention, and with frustration so hot no other man could have born it, Achab turned away from the nebula. For the marines he had left to eradicate the corsairs, freebooters and renegades had failed in their task: they had done nothing more than stir up a hornets nest.

And those hornets were heading straight for the Star Kraken's homeworld.
