I don't know if it's already been discovered and talked about, but I'm curious to know. When you go to "set destination" on the Navigator, you can see there's rings outlining the different planets and moons. If you look beside the Crucible, there's a ring about similar size to it. What could that be for? -My thoughts would be either: An offline/private mode, similar to Gears of War, where you could play different game modes against bots. -A Firefight/Survival mode such as Firefight in Halo: ODST and Reach. -Perhaps a Forge Mode? (But fit for Destiny obviously) That is, if it's even a piece of the hub that's missing. For all I know it could just be aesthetics, but it definitely looks suspicious... Leave your thoughts below! What would you want that option to be?
