Imum Coeli (IC)
The Imum Coeli ("bottom of the sky") sits opposite the Midheaven, beneath the earth from the observer's view. A planet's IC line marks where it was exactly anti-culminating at your birth moment.
Near an IC line, the planet works on the foundations: home, family, belonging, the parts of life that don't face outward. People often describe IC-line places as feeling significant in a private, hard-to-explain way.
