Saturn transit conjunct the IC/Nadir?

All transits simply act as background influences until they make a mathematical aspect to another planet or angle ie: Ascendant and Midheaven.

“This marks a time of considerable inner "re-working”. In terms of outward signs of achievement, this transit may be the most unremarkable of all the Saturn transits. However, near the end of the transit, and certainly later than that, you will recognize this stage as a critical one in which you made some life-changing personal and psychological advances and developments. During this stage, you are working on solidifying your identity, exploring your roots (where you came from), so that when Saturn begins its transit through the fifth house, you will be ready to differentiate yourself from others and embark on some important work on your ego. For now, however, you will face issues surrounding your attachments to the past. Sometimes this manifests as literal re-organization of your home. Moving house is not associated with this transit as it would if, for example, Uranus was the transiting planet. If moves are made, you might encounter some resistance in yourself. This is not a time when you feel particularly brave in the outer world. However, reorganization in your home, and more importantly, in your soul, embodies the true nature of this transit. Many will go through a major “spring cleaning” inside. Limitations that came from early family conditioning will be brought to the fore. At first, there may be some frustration with your life to date, and how you have limited your opportunities because of early conditioning. A feeling of being alone and unsupported in life may dominate the early stages of this transit. Sometimes, delays and slowdowns are experienced in the areas of health, mobility, and career. As Saturn moves closer to the fifth house, a feeling of some kind of mastery will empower you" http://www.cafeastrology.com/saturntransitinghouses.html
