Those about to die.
Above the Hellworld Avernus floats a great line of fortresses. They are impregnable, mighty, and utterly inadequate. One the few constants in this turbulent age is that every major void battle in the helheim system has seen their total destruction. As such all who choose to serve aboard these doomed fortresses are told that their positions will fall in the event of any serious invasion. This has had an interesting interaction with the typical Avernite mindset.
"This is Publius we have the latest estimates from the Admiralty. The most optimistic realistic projections put the elimination of the final orbital at 72 hours from the start of the engagement. Gentlemen, I do not feel optimistic."
It was perhaps inevitable that the Avernite view sacrifice would make the orbitals a somewhat sought after post. resulting in a somewhat overqualified crew for a position who's stated duty was to ensure the defenses performed at maximum capacity throughout their service life.
"As such, I am setting the absolute projected deadline at 48 hours from initial engagement. I now open the floor to any suggestions."
"Masada here, my tech priest has some reactor modifications that will significantly increase reactor output, they don't induce catastrophic failure for at least 50 hours."
This mostly resulted in a rather interesting reinterpretation of that duty when projected service life dropped from centuries to hours.
"Any fallout?"
"they're pretty sure it'll get anyone directly involved shot for tech-heresy."
This was further amplified by the kind of reckless courage only imminent death provided.
"they can get in line. Alamo you are going to miss most of the shooting on your present orbital track."
"We already have a solution. We're rigging up a pulsed plasma drive using our torpedos. we'll get a bit toasty, and won't have enough to spare for the scheme Vukovar's cooked up but should show up just in time."
"Good. better bleeding than late. Vukovar, tell me about your plan for our spare torpedos."
"If We start firing them early with the engines programmed for a delayed burn, and we thicken the swam by throwing them into the void any way we can with preprogrammed staggered burns we can hit the enemy fleet with a massive volley. We time everything right and we can have about half our torpedo inventory hitting them with the strike fighters. Most won't have the speed to really be a threat, but imperial point defense doctrine calls for hitting the torpedoes first, and I doubt they'll break from that. I figure the flyboys would appreciate something to draw fire."
"May as well have them go off in the void rather than in our holds. Get heaving."
and so it went. guns, were overcharged, scuttling charges were optimized, reactor meltdowns where planed out, reactor shielding was stripped, sacred taboo where ignored and machines intended to last for centuries were worn down in days in exchange for even the slightest increase in performance. Stewards who had maintained their fortresses for decades made ready to consign them to the flames, forsaking any hope of survival to instead stoke the flames high enough to catch just a few more of the enemies ships. Thoughts of the next battle where reduced to ensuring a copy of the logs made it onto the planet so that the next set of stewards could learn, and sell themselves more dearly still. The men do not hesitate, they do not despair or waver at their duty. To live on Avernus is to die so that others may live, to suffer so that you may forge yourself into a shield for those who cannot shield themselves. To the men and women aboard these doomed fortresses, there could not be a more fitting end.
