The Blue Suns are a successor chapter to the White Scars based on the heavily forested Death World Antarius, located a few light-years off one of the major Chaos invasion routes from the Eye of Terror. The chapter prizes the gathering of knowledge and tactical flexibility over fanaticism, view the Codex Astartes as merely one tactical possibility of many, and are overall pretty optimistic.
Tropes exhibited by the Blue Suns include:
- Author Appeal: The somewhat silly approach to 40k lore and the backstory is largely due to StarSword preferring the parts of the mythos that don't take the GRIMDARK too seriously (e.g. the Ciaphas Cain series).
- Enemy Mine: They have an extremely tense relationship with an Eldar Craftworld that settled down near their territory, one that developed after the two sides were forced to work together to defeat a particularly bad Chaos incursion. Most of the time it amounts to "we stay off your planets, you stay off ours," but they do trade information once in a while.
- Future Imperfect: The Blue Suns are so named because their founder ran across a partial DVD set of Firefly and didn't quite understand what he was looking at. Their battle song is the Firefly opening theme.
- Highly Conspicuous Uniform: Chapter colors are two shades of blue and white.
- Humans Are White: Averted. Their original recruitment stock was descended from central Asians, same as the White Scars, and they aren't picky about which planets near Antarius they recruit from: their current chapter master is ethnically black.
- More Dakka: They prefer fighting at a distance and concentrating an unrelenting hail of bolter fire on their target.
- Original Character
- Super Soldier: Duh, Space Marines.
- Proud Scholar Race: The Blue Suns make a habit of carefully studying the tactics used by other armies to learn what works and what doesn't. For example, faced with the Tau, they've learned that the Ethereal is the weak point and prefer to launch a diversionary attack to draw off their forces, then deep-strike a couple squads of Terminators right onto the Ethereal's head, then quickly press their advantage to rout them.
