R226 System Entry Encounters
Whenever you hyperjump to a new star system you must check for a system entry encounter immediately upon arrival.
To do this, refer to the proper system in R207, and roll 1d6. After this event, you can begin moving in your starship to any
planet or the asteroids (see R212G).
Once you undergo the system entry table in R207, you need not check it again until you hyperjump and arrive at a new star
system. System entry results are not required if you move from one planet to another (or to/from asteroids) within a star
system.
