In Star Trek Klingon Academy Demo Mission 2: A Dish Best Served Cold, you must abide by the Klingon proverb about revenge.
Hunt down the other Romulan ship that crossed your boarders. Chase them through gas giants and planetary rings. Don't let them escape. Don't forget though - you are near gorn space, and they hate for their boarders - or even contested space, to be entered. Show them the might of the Klingon Empire!
