Now, I know what you're all thinking looking at this motley crew, so let me answer some of them.
4? Yeah Knights usually deploy in Lances of 3, but only Butch and Ostia have seen real real combat so they've been given two novices to supervise. The Forge World they are trying to liberate is also quite treacherous so all Lances are being deployed with an extra unit if possible.
Gregory's jaw? Its iron because his glass one broke. Speaking of Marmalard, his family made their fortune off high end ration preservation and canning. His callsign is Jam Boy.
Ostia's scars? Shrapnel from not positioning her ion shields during her early piloting years.
Butch looks like a dockworker? Yeah that was the inspo. His specialty is breaching and his knight has two giant Hades Drills on it.
Uhhh.... I think thats everything you could possibly want to know-
OK NO I KNOW WE'RE GONNA HAVE TO TALK ABOUT DUKE.
Geez ok, look. Our RPG groups are known for chaos. Our Rogue Trader group is similarly unhinged. But Duke...
Duke (Thats not a title BTW his name is just Duke) is from a Deathworld where feudal waring houses have been using Knights to fend off vicious, giant lizards and the other houses for millennia. They've only juuuust been brought back into the Imperial fold and this is his first mission off world.
Its absolutely unhinged. The man cant even make the sign of the Aquilla right. Everything is a lizard metaphor. He's got a distillery hooked up to the cooling systems in his command throne.
It's amazing.
