Humans for Hire

In the future, humans find employment as galactic mercenaries, with a few stipulations: they're not allowed to be hired by governments and they're not allowed to declare war. In return, the rest of the civilized galaxy isn't allowed to declare war on them. One such company is the Bulldogs, and one such client is Gryzzk. The contract is theoretically straightforward - but it gets complicated in short order, leading to Gryzzk getting into a situation he never dreamed of when he left his homeworld. To be fair, nobody else expected it either.
