I also have barren areas in the Kingdom, made that way by too much magic hitting the land. So anyone hoping to get out of trouble in an area like this using whatever magical skills they have is likely to find themselves shaking hands with the Grim Reaper instead of getting to live a long, prosperous and peaceful life elsewhere. And all magical species know this so they tend to avoid being in these areas at all. Naturally there are stories to be had in how these species avoid these areas (which is not as easy as it sounds given the whole magical realm has experienced war so damage has been done almost everywhere. It's a question of degree).
Naturally there are settings like the Palace and the Queen's coastal resort which are as close to perfect landscapes as anywhere is likely to be. Most of the villages and towns have avoided a lot of the war damage but the areas just outside them are not always that lucky (which is why avoiding these barren places is not always straightforward). Naturally residents are keen to keep their villages and towns as beautiful as possible which is why the sprites with all their trouble making and fighting are the most loathed of all magical species. (Even a wicked witch, as long as she says keeps a nice garden, has a better record than them).
