The partnership lines
Venus line
The single most requested line in astrocartography, and for good reason. Venus on the Descendant puts partnership in the foreground: you are met, courted, chosen. People approach you here rather than the other way round.
Moon line
Moon on the Descendant makes closeness fast and feelings legible. Bonds form quickly and run deep, which is wonderful when you want one, and overwhelming when you were only passing through.
