The galaxy is a large place and there will always be need for private security organizations. Whether it is to protect a settlement or mining operation; to deliver an important cargo; to steal some resources or tech, there will always be a market.
The Crimson Skulls is one such mercenary group. Founded five years ago by a group of disaffected Caliphate warriors they have earned a reputation for fiercely completing contracts. Over the years others have joined from various paths. There are former military personnel from multiple nations, former colonists, victims of pirate raids. Their equipment may not be the most high-tech, their vehicles might be in need of repair, but in general, they are ready and willing to complete the job, no matter what.
