This set doesn't seem too bad, but it is very peculiar. That sword is "guarded" by some falling axes, but the back of the structure looks to have an opening large enough for someone to climb through with ease. Maybe there is a trap back there, I'm not sure as I don't have the set. I also find it odd that an item of importance would be stored in this tiny little building and rely only on traps to protect it, and not even include a door.
The jail isn't too bad but is pretty unrealistic. A prisoner is suppossed to be kept within a secure building. This is not secure at all. However, this is a mistake Lego has made with several of their sets in the past, as they seem facinated with jail cells.
The problem with a set like this, as compared to say, The Black Monarch's Ghost, is that you don't really know what to do with it. The Black Monarch's Ghost was meant to be a little guard house outside of a larger castle, and as that it functions well. With this set, there would be no reason to put the jail next to a larger castle, as the larger set would likely house a jail inside of the building itself. The "treasury" just seems awkward. Although these sets were built with modularity (is that a word?) in mind, they just aren't very useful.
But, at least the set has some decent pieces, so it isn't a total loss.
