You are being sent to a foreign planet to deal with a problem that came back to haunt us..MAREDAN. Computer A.I. that went insane. This was an entity we have not heard of for 42 years. An issue that tried to take us out. It seemed to have returned, and in greater forces. We must deal with this before everypony gets in danger.

(This will loosely be based on System Shock 2 since I've been playing it more lately.)
