One important thing to keep in mind while developing your setting is to not be afraid to change your mind about things. For example I am contemplating a change that would affect the monasteries in Dòkràkr, the Rìyàdak, and the Dekmekom, as well as the populations of all of Dòkràkr. Until you start playing in an area it should be considered as open to revision.
Now with that being said, it must be stressed that one should consider all changes carefully, as some will have far reaching effect, one needs to consider if the change is worth the amount of work it entails. Again using the possible change mentioned above, I have been mulling it over in my head for a couple weeks, trying to decide if I want to make it and exactly how the new idea is best implemented.
