Plus:

If a biome has a king, like Gondor, you can only protect house (if you're not Gondorian), if the kings approve it, except Rhun ("the land of custom facs" :P). You can only build something near the fac's cities, villages etc, if kings approve it, but you can build anywhere if you're min. 1k blocks away from it.
