Your initial assignment:
The Sereld family is one of the great noble families of Nerath. In the wake of Rhumorril's re-conquest, they -- like the other great noble families -- have lost many of their fighting men. With the tensions within Nerath rising, they -- like the other great noble families -- have taken to hiring mercenaries to aid in protecting their lands from the pockets of goblins, kobolds, and other creatures that posed a threat to their peace and security. (It is something akin to a "seller's market" when it comes to mercenary services.)
The Sereld family has a reputation of fairly treating those in its service, with advancement being affected far more by merit than simply family name. They also have a reputation for being judicious in their use of force, which -- to some -- is a negative in that there is less chance for glory in battle. (Of course, that also means there's less chance for death in battle...)
You have been in their service for a few months (or longer if you choose) and have met and become acquainted with the other PCs in the course of your duties. Recently, you were given a new assignment: bodyguard detail for the family's representative in the capital. What was historically an assignment for the soon-to-retire in their service has been deemed important enough to assign to a more youthful crew.
You travelled to the capital in each others' company (a journey of roughly 600 miles) via stagecoach, horses, etc. which took a little over 2 weeks time. You have been in the capital for just over a week and have been getting settled into your role as bodyguard for Naso Sereld. Naso is in his 30s, and is a third cousin of the head of the family, Duke Iaskelo. He's been their representative and envoy in the capital for a few years (since the middle of Risach's reign).
