Finally have a proper Stormtrooper HQ
I confess I was never sold on the overcoat originally but added it so he would stand out next to troopers but now it's all painted I'm really glad I did It inspired me to add a little lore for them:
The Inquisitor Lord [REDACTED] knew he had found an unpolished gem of the highest raw quality when he stumbled across Arukan. Not content to draw their great clans into mighty regiments of the Imperial Guard he saw too an opportunity to fill a particular need of his own. Formed in secret along with the clan regiments, what was first a simple regimental number would turn into a name in its own right - not the 501st Arukan, but simply "the 501".
The 501 intentionally distance themselves from their cousin regiments, for they do not live in the same galaxy. Not for them the glory of great wars against His foes, or heroic defence of His domain. Instead they function as a lightning reaction force, ready to despatch at a moment's notice to wherever their lord needs to do whatever he demands. From the seemingly innocuous escort to the most daring of Kill Team missions they carry all out as if the Imperium's survival hinged on the result.
To the line regiments of Arukan the 501 are a question they know better than to seek the answer to. While their obvious talent is highly respected and appreciated - not least when the Stormtroopers of the 501st provide vital covert assistance - their complete and utter disregard for anything other than the mission is confusing and sets them ill at ease. Without honour, what is a soldier?
To the 501 the opinion of others counts for nothing. They have no need for honour; there is only duty for they are not soldiers but tools. Their relentless pursuit of victory no matter the cost has won them a string of improbable victories, most never known to anyone other than the regiment and the Inquisitor Lord himself. How many times have entire systems - or perhaps more - been saved by their timely actions? The 501 care little, for victory is all they want and duty all the reward needed.
