The Zephyr are a race of machines even more advanced then the Geth. They are usually a dark blue, violet, green, or red. They vary in shape and size though most are shaped like Humans. Others have the appearance of Krogan and Turians. They have no visible eyes or ears but have extremely good vision. They use an advanced form of nanotechnology that allows thm to heal over time. They 'evolve' by assimilating other AIs and VIs.
Nobody knows where the Zephyr come from or who made them. They werent even discovered until they started a war with the Geth. The Zephyr have made it clear that they wish to assimilate the Geth and evolve. They apparently have been doing this for decades meaning that there are other machine races in the Galaxy.
