>Watch Fortress Interius
My deathwatch team. They specialize in action against infiltrating xenos threats, and have had plenty of run-ins with genestealer cultists and dark eldar. I've written a paragraph or two of lore for each of the models in the team.
>DELTA
The hidden inquisitorial team working from within the same watch fortress, logistically disguised as a janitorial team.
>The Kill Counts
Also attached to the watch fortress, a team of kasrkin soldiers tasked by the adeptus administratum with safeguarding and procuring ammunition stores for the inquisitorial fortresses. Really meticulous about ammo logging, as is to be expected.
>The Fire Brigade
Working in the same sector as the above teams, and frequently alongside them, a team of Navy Voidsmen. Their red-orange suits are used as camouflage for when they inevitably set everything on fire. Their unit is single-minded in purpose, and are basically in universe competitive sweatlords.
>Angels of Absolution
My oldest team, and their lore was built from an older campaign started before KT18 released so it's got a lot of details and sounds really fanfictiony, but it boils down to being an isolated force consisting of both primaris and non-primaris marines that are not currently in contact with the chapter.
>Emperor's Shadows
More of a painting and modelling exercise and wanting to use this obscure chapter than a lore interest. Honestly, I feel like "they're space marine ninja samurai" is enough character.
>Confessor Reude's Retakers
Sanctifiers team based on a group of flamer-wielding fanatics led by the titular confessor that appeared in my current roleplaying campaign shortly before the reveal of the box. Their rank-and-file have a pretty high replacement rate, but there are some more notable characters among them.
>Dark Mechanicus team
Actually never named these, but they're obsessed with perfect measurements which caused their fall to slaanesh. Really fun team to kitbash.
