Beyond the planets
Beyond the ten classical planets, a chart is anchored by a few other points worth reading.
Ascendant (ASC) — the sign rising on the eastern horizon. It shapes how the moment meets the world.
Midheaven (MC) — the highest point in the sky. The vocational signal, where the moment's energy aims.
Chiron — a small body that moves between Saturn and Uranus, read as a sign of where the long-way teaching lives.
North Node — not a body but a mathematical point of the Moon's orbit. It marks the direction of growth.

A chart pattern is a meaningful geometric shape formed by three or more planets connected by aspects. These configurations are read as unified dynamics rather than individual aspects.
We split patterns into two views. Classic includes the shapes established in modern astrology — T-Squares, Grand Trines, and more. Extended adds geometric configurations that carry meaning beyond traditional astrology: closed shapes formed by any combination of aspects.
