A number of people have suggested that we have an exploration type quest and in order to get away from the pre-information U tube trap I would suggest the quest has a number of RNG seed points and takes the environment into a range of routes depending on which seed has been assigned as the quest unfolds. The obvious one is the infinite forest where the RNG seed kicks in when the gates are activated. This could be an infinite quest(excuse the pun) with intermediate rewards which are added every couple of weeks. Another way to keep the mystery would be to use the jump gates with the destination varying at each jump gate activation depending on which RNG seed had been assigned to your character. The work load could be reduced for Bungie if some of the Crucible maps were used. to warp into.
