                          They must "die off" so that other Empires might survive...
                            been off at Spore attempting to "weed out" an Empire...

                   Having them use their abilities to  up-grade planets...
and at the same time raise another Empire with their help... all before we have their Empire fall....            (they will still own their solar systems as a large "non-playable" Empire...)
