A user going by the name of Skruggle has posted several images on reddit of one of two areas he managed to glitch in to in Destiny . As well a name for the bunker has surfaced suggesting it is possibly called RAS-2. No one is yet to work out exactly what relevance the name holds to the game, if any at all. 
Nothing is known at all of the areas we can see in the images other than the fact that it isn't content that is to be externally installed to the game, it's already there which means putting a zip on the crowd of people that aren't happy with the expansion pass content expecting to pay for content that should already exist in the final product. Clearly this is stuff that was there from the beginning.
The ghost like entrance in the second Image is rather awesome and makes me wonder whether there is more secrecy behind your little companion.
