December should be The Month of The Traveler where new stories are introduced, new weaponry, new gear, new everything. "The Traveler came to help us so we should do the same." Like the Festival of the Lost where you get candy, The Month of the Traveler is about giving, helping others, and spreading joy/camaraderie in-game. There should also be new holiday specific Bounties (idea: you complete one of the bounties by giving gifts/glimmer to the robots and people walking around the Tower or help them with specific tasks they cannot do on their own or even dancing/waving/playing side-games with a set number of other players). I have so many ideas for Destiny it's insane.
