A Slave is a Slave

The Galactic Empire is slowly 'welcoming' into the family of civilized worlds those systems so far off in the backwater of the galaxy that they have been overlooked and ignored for the past 500 years or so. This is purely routine work because every planet offered the chance has eagerly accepted the invitation. Mainly because the enlightened Empire lets the planetary government continue to rule and do whatever it wants. . . with a few minor restrictions of course; and because the they are shown what happens to planets who decide not to accept the invitation.
