What I would do is hide a secret cache of Armor Locks.

Something epic that showed symbolism of these times. A dark room that's only source of light came from a blue-flamed torch, under witch would have a plaque with the Septagon on it and it would say "The 7th Column". The back wall would have the signatures of all the employees at Bungie written on it. And when you walked in it played The Siege of Madrigal. The symbolism is that we, the community, are the torch. For Bungie is still running dark, but were burning bright. And blue.
