It's like a park. I like to think it is a great place where Gardiams go to unwind when they have some time off. To play soccer or with the bouncy balls [there are two of them] To have a picnic and watch the sum rise or set and relax with Ghost and other Gardians. I am sure Guardians don't spend all of their time on missions. Probably go for a few days then come back and get some time off before heading out again. If nothing else it is a chance to take a long shower and get the Thrall smell out of our gear [if that is even possible :-P]
