Who are the Zetas?

The Zetas are a group of Service-to-Other Beings who are assisting this planet and it’s people in the transformation from 3rd to 4th density. This Transformation is happening now, and will be completed sometime after the passage of the 12th Planet, and the resulting Pole Shift that this passage will cause. See:
