The thing about Artem, it's a damn hard city to live in if you haven't got creds and plenty of them. For creds you need opportunities.
The thing about opportunities, they're thin on the ground for Orcs. One of the most reviled races in Artem. And if you're an Orc, stranded outside of the immense city walls, left for dead on the front lines of Artem's roving monster problem, then you're doubly screwed. Like Oshbob.
The thing about Oshbob, he's pissed! Missing a couple of important appendages, but with a will to survive like few others, if he can make it back to the city, he's determined never to be subject to the whims of the city's ruling class again. He's gonna make something of himself, no matter the cost to those around him.
