Camelot was an odd place. Famous for its candies, assasination attempts every month, and an invasion every other year. Certainly, the people were odd. All some people knew was that living here was an adventure, whatever your station. Others did not feel the same, and had left the city for somewhere less exciting.
Servants at the castle saw everything, or most things. One thing anyone learned in Camelot was that servants went unnoticed, most of the time. They heard things, they saw things, and they never shared it. Ever. Unless you happened to be part of the grapevine, which was everyone who mattered.
In addition to the oddities of Camelot, there were the secrets. Oh, there were secrets. Everyone knew that Arthur liked Guinevere, and they all knew there was a distinct possibility that Morgana was evil. Not that they would say anything. After all, the drama was enticing. Then there was Arthur's manservant, the worst-kept secret in the city.
He was kind, always laughing, and rather stupid. But not really, because anyone with half a brain could see that his brain his was working just fine. Most of the time. One thing all servant knew was that he was terrible at making excuses, and given his situation, that was bad. Being the magnanimous people they were (Also, it was all building up so nicely, and they didn't want to have it collapse before it was the most dramatic thing it could be) they helped.
An angry prince, storming down the corridor's searching for his manservant could easily be stopped with a "Yes sire, I saw him earlier. It seemed as though he was heading outside of the city." And then you paused, oh so deliberately, "Probably for the physician."
And if, perhaps, that prince or someone had seen something odd (People knocked out by falling bricks, or branches, or even plates flying) you would speak, perhaps a little too loudly, "I knew that the wall was falling apart." Not too obviously though, you wouldn't want them to get suspicious. The plates were unexplainable, but there was only so much an army of servants could do.
Most important, though, was paying close attention. If you didn't, you might miss something, and then you would lose. Once upon a time, there had been one for Merlin getting accused of sorcery, but no one would take those odds anymore. Currently, the odds were 3 silvers to 1 for an assassination attempt ( 2 to 1 for Morgana being the culprit), 2 to 1 for Arthur being knocked out at some point, and 4 to 1 on what would happen to the next patrol.
Most of the servants were fairly certain that betting on the conciousness of your prince, the likelihood of getting attacked, or the prince's manservant dying(but not really, because the dungeons couldn't hold him, and he hadn't been accused in a while) was odd, but, they were happy, and the odds were good that they would get paid.
Camelot would be saved, they would have underappreciated roles (Did they really think that everything ended up that way by chance? The servants worked hard for that) and life would go on. As it always did. As it would continue to do. And if the servants, as a whole, were committing treason, then what was new?
