Capricorn on the inside, Gemini on the way in.
Your sun in Capricorn (earth, cardinal) is the engine — what grounds at the centre, what starts when you are at home in yourself. Your Gemini rising (air, mutable, ruled by Mercury) is the door — the way you arrive in a room, the first read the world takes of you, the body you walk in.
Strangers tend to assume you are witty and detached — that is the Gemini arriving first. Then they get to know you and discover the Capricorn earth underneath, which can be a quiet contrast — light surface, weighted core.
Reads as Gemini until you trust them; then Capricorn comes through. The cardinal-mutable mix means you starts on the inside while adapts on the outside — internal and external rhythms are different, which is its own work.
