I like this as well. Very useful. One of those places in every city makes it easy and convenient in a game and I can see its merit. Useful for just starting out, clearing some woods and collecting some bounty, maybe making a name for themselves. Eventually, they may catch the eye of one of the bureaucrats in the house which will bring up their status and up the ante of their quests. Can see it working well for ongoing campaign usage and always useful to dole out some rumors or plot hints. Great idea! Go to Comment
This is interesting - a dedicated 'embassy' for the king. I'd assume the local nobility would be required to maintain it as part of their fealty to the king. I could see that becoming a point of interest with different nobles coming up with ways around this arrangement somehow, Go to Comment
Such elements can easily spice up a game. A character finds an old shield in a dungeon with an unknown to him coat of arms and begins using it. Turns out the house it belonged to was expunged from history by an enraged king - the father of the current king.
Might make the next visit to the capital city a little more exciting. PC's might want to brush up on their heraldry skills on their next character :)
As for commoners not caring about heraldry, I could not disagree more. It is rather important to know whose boots you should lick exceptionally clean, and whose you must run from.
