Thanks! I have absolutely much too much fluff. The short story on the name is that it comes from the chapter's founding, when a squad of scouts on a training mission crushed a heretic that had declared himself a king and denied the Imperium. Hence their chapter icon of the sword shattering a crown. Early on I made decals of it for all my guys & vehicles, which really made the army standout and gave it a lot of narrative momentum.
The chapter's actually collected a long storyline over the years, connecting together all my Imperial armies and introducing the characters, with the plot influenced by my friends' armies I've fought regularly, the directions my collection has taken, etc.. There's a timeline and a couple more action photos here:
