One thing that kept the disparate parts of Branan civilization linked was the easy communication between the physical and electronic worlds. The Second Lifers could of course speak with their meat-bound relatives in the physical world via anything from basic speakers to advanced robots. And the First Lifers could visit the electronic world of the Second Lifers through the use of various virtual reality gears. Many First Lifers actually gained the money they needed to live comfortably in their Second Life by working inside Second Life systems. Money flowed freely back and forth between the physical and electronic worlds, and many First Lifers spent their time learning about and experiencing the worlds they intended to visit once they entered their second life and could travel the stars at lightspeed.
