The Traveler's Light Reaches the Omniverse?

[Demetri Malius]

So I was thinking about bringing in the Vanguard from Destiny, as well as possibly starting up the random appearances of enemies such as the Fallen, Vex, Cabal, and Hive. I have some ideas, but first i want to run through and see if any of this is possible. I should also say that without much help, this will most likely happen in 6 months to a year from now. If needed I can post some pictures and info for those that are not familiar with the characters or lore.
