Message Chip - A small blue computer chip which is used to hold messages. They can be encrypted in which case, the reader will need the key code to read the message.
Tight Band Message - A message sent via Subspace in a tight directional signal. The signal can not normally be picked up by anybody except if they are on the line in which the message is sent.
Subspace - Normal space, as opposed to Hyperspace.
Hyperspace - Hyperspace is a second dimention which is smaller than Subspace, which means that if you cross into hyperspace, then move 1 km, then cross back, you will have moved 10km in Subspace. Hyperspace Jumps are used to move quickly but they only graze the surface of hyperspace. To move between quadrants you have to move a long way and so you must enter hyperspace toatally. since it takes massive amounts of energy to open cross the hyperspace barrier, only Jump Stations can open Intersystem gates to and from hyperspace.
Virain - The Virain are a battle weary system of people who are holding out from the empire by using their small fleet to defend their home world. They are rumered to be engaged in several secret attacks against the emperial fleet and the emperial home world. They regard the Poliniss as allies.
Poliniss - Poliniss is a strong prospering trader world and the world you were born on. They trade with both the Virain and the empire. However, they are on the brink of joining the Virain to defend their old allies against the new force. But since you are a mercenary, you can't be expected to join in. Can you?
ZIF - Zero Insertion Force. An interface for plugging chips into a computer which will not break the legs off them.
Jump Stations - These are space stations which allow you to move into other quadrants by opening gates to and fom hyperspace when requested by passing ships. They reserve the right not to let you jump and are ultimatly in control of the system in which they are situated.
