Drekkana (D3 Siblings Chart)

Drekkana divides each sign into three parts of 10 degrees each. The first decan maps to the sign itself, second to the 5th sign from it, and third to the 9th sign. This chart primarily reveals information about siblings — their number, nature, and your relationship with them. The 3rd house lord's placement in the D3 chart is the primary indicator. Mars's strength here influences courage and initiative. Some astrologers also use Drekkana for understanding one's own vitality and willpower.

Your Drekkana chart reveals sibling dynamics, courage levels, and your capacity for initiative. It complements the 3rd house analysis in the main chart.
