The Heart of the Lion — a Royal Star of Persia, watcher of the North and the summer solstice in antiquity. Regulus shines as the brightest star in Leo (and crossed into Virgo around 2012 due to the slow precession of the equinoxes). It is the most prominent fixed star of the kingly tradition.
Regulus is a star of power, leadership, and ambition — the king-making star. Its nature is Mars-Jupiter: bold, magnanimous, sometimes ruthless. Conjunctions to natal points raise that point to a place of authority and visibility, but with the classical caveat: "success only as long as no revenge is taken." The gifts of Regulus are forfeit the moment the one who holds them turns to vengeance or pettiness.
Traditional readings emphasize the rise-and-fall pattern: Regulus brings power easily, and takes it away when integrity slips. The crowned position is conditional on character. With its 2012 ingress into Virgo, modern astrologers read this as Regulus shifting from a "king" to a "servant-leader" archetype — the ruler whose authority comes from service rather than dominion.
Manifests as: prominent leadership, military or political distinction, sudden public favor, charisma — followed by tests of generosity and forbearance.
