Colony Ship

The Colony Ships are ancient spacecraft that appear to be remnants of the golden age of humanity.

History
It is unknown what they were used for exactly but in Old Russia there was a number of abandoned vessels surrounded by gigantic walls to protect them. Leading up to the walls are numerous vehicles filled with ancient human corpses, implying a possible rush or panic in an attempt to read the vehicles.

Behind the Scenes
Not much is known about the colony ships, they have only been seen in Old Russia and mentioned a few times by Bungie. When mentioned in the E3 gameplay commentary the commentators were intentionally vague on the subject of the ships.
