 Once Operation Unity succeeded in subduing the Andromedans, the surviving Magellanic forces (which had held out in exile among the Fringe worlds) took to re-building their fallen empires, though it would take a long time for any of them to approach their former glory.The original location of the Tholian Will was M81, a galaxy outside the Local Group.Before the Seltorian revolt, it was controlled completely by the Tholians, with the exception of isolated nebulae from which the Nebuline species helped support M81 piracy.
