Have you ever sat in the hangar and listened to the loudspeaker? The lady occasionally says a random thing like "ship # (insert number) 3 cabal prisoners aboard" which got me thinking about this idea. How does a event spawner in the tower sound? There is always people at the tower so if a event (say an attack by the hive or fallen) comes in all available guardians would be asked to defend the tower. I'd like to see this one day if possible as I feel it would help get fellow guardians to be a bit more social. Peace fellow guardians! -LivinDeadLove
