A long time ago, when people all lived in the
kingdoms, they were surrounded by pales.
pale. A stake or pointed piece of wood; fence made of stakes used to wall off communities. In current times, social norm dictates that one should stay within the confines of the pale.
The pale is not a fixed place in time; at any given moment, one may leave the psychological realm of the pale.
We are still living in kingdoms, and the pales are still ever so sharp.
