This is Manrich Proudglass, a halfling thief / assassin. I generated the pic in Midjourney.
Here’s some backstory I wrote for the DM at the start of our campaign. For context, the campaign is happening in a continent the DM created from scratch. The Peacekeepers are the national police force; Manrich started the campaign busted back to a grunt for reasons unknown to both the character and I. I assume the DM knows what happened. 
It’s pronounced Man-REEK. He’s fussy about that, and doesn’t appreciate the obvious jokes.
Chaotic good.
Recruited into the Peacekeepers, Manrich’s talent for sneaking and skulduggery meant that he was soon seconded to the Intelligence department. He did well and honed his skills there, but was busted back to being a regular grunt for some unspecified transgression.
Manrich’s missions in the Intelligence department tended towards the clandestine - burglary, spying, infiltration and sometimes “direct targeted action against high-value individuals”. During his time in the Peacekeepers Intelligence department, Manrich used his skills to serve the Empire, but often his conscience would get the better of him and he’d go “off-mission”, solving the problem that he thought he ought to solve rather than the one he’d been tasked with. He characterised this as having a high degree of personal autonomy, but maybe his superiors saw things differently… which might be why he finds himself back in the Peacekeepers main force.
Manrich doesn’t have much time for petty considerations such as paperwork, rules, mission parameters or the finer details of who actually owns that thing in his pocket. The ends justify the means, but those ends are usually on the side of the angels.
In terms of gameplay mechanics, he’s first and foremost a thief, but I put high points into charisma so that he could lie, cheat and persuade his way to his objectives. It hasn’t been that sort of campaign yet though, and in practice his role is to skulk in the shadows and deal damage with Sneak Attack (a tactic that has the added bonus of annoying the DM no end). In our last session, Manrich abandoned his natural caution and emerged from behind the upturned table that was his home for the battle and sprinted across open ground - getting peppered with arrows for his trouble. He won’t be making that mistake again.
