Descendant
The Descendant is the point of the natal chart on the western horizon, always exactly opposite the Ascendant. It governs committed relationships and the qualities sought or projected in a partner: what the rising sign leaves undeveloped, the setting sign describes in the other. Planets near it give relationship a central role in the life's design.

Overview
The western horizon: where the light of the self is handed over to the other.
The Descendant marks the setting point of the chart — the sign sinking below the horizon at birth, and with it the qualities sought, admired or fought in others.
Mythology
To the Greeks this angle was the Dysis, 'the setting': the gate of the west where the Sun completes its arc and descends toward the unseen. In solar myth the west is the place of surrender and encounter — Helios stepping from his chariot into the golden cup that carries him back across the night sea. Traditional astrology read marriage and open enemies here with equal confidence: both are bonds between equals, and both begin where self-sufficiency ends.
Interpretation
The Descendant is the point on the western horizon, always exactly opposite the Ascendant. It governs significant relationships, partnership, and the qualities we tend to project onto others or seek in a partner: what the rising sign leaves undeveloped, the setting sign describes in the other. Planets near the Descendant give relationship a central role in the life's design. Read together, the two ends of the horizon form the axis of self and other — the negotiation between asserting an identity and completing it through someone else.
