Originally my thought was to make the ward of dawn a physical barrier from the outside, mostly for the purpose of controlling doorways and enemy movements. Perhaps I should have stuck with that.

In this version, enemies could not enter a ward. So a properly placed ward could block one door while you watch the other entrance.
