The Spirit of the planetary body is able to focus all of the powers that fall under their domain through you, for you in order to influence and assist you in all you do. For a cost you and those around you that you target can be pulled directly to the surface of your planetary body, with all targeted protected for the trip. No matter what kind of surface your chosen planet has it will always be livable and buildable for you.
