   Why not have a young spacefaring civilization find an unused,   
   uninhabited orbital, settle down and then discover why the original   
   inhabitants abandoned the structure.   
      
   Perhaps the billion year old orbital has drifted to a region of space   
   where it's subject to neal-luminal particle rays from a medium sized   
   black hole when some matter happens to replenish its accreation disk.   
   Such a threat might be both suitably difficult to detect to allow for   
   settlement and then become painfully obvious when the matter hits the   
   fan. If the orbital structure is able to offer some shield from the   
   radiation it might even allow for survivors that have lost their space   
   capability yet retain some original tech.   
      
   Or possibly one might have multiple such incidents, resulting in an   
   orbital with layer upon layer of archeological remnants of previous   
   civilizations on various tech levels and biological preferences. Nice...
