Neural implant

Neural implants are very small computing devices installed into the brain of a sentient being. One primary use is to have a Class-1 AI always at your beck and call.

But the most important reason, is for universal translation, which allows any species to speak to any species. The implants are advanced enough that the person doesn't experience any lag, and the person may even see the other person's lips match the translation if their implant is good enough.

Due to the importance of having access to a universal translator, most sentients in the galaxy have implants.

Another reason for neural implants is access to the Nexus anywhere, as long as the user is in range of a subspace communications buoy.
