General concept
The overlord is in fact a higher version of the controller, it doesn't control just a pack. But can also control workers and more. These Ch'thda are relatively smart and might also communicate with the humans. They are the ones that set out the Ch'thda tactics.
Combat
The overlord can have some defense mechanism? Or has a default defense pack around that has only the task of defending the overlord?
Art
Nothing so far.
