Scorpio

Fixed water. Feeling that does not move and does not surface — Vṛścika holds, and what it holds is under pressure. It is the natural sign of research, of the hidden, and of things that transform by going through rather than around.

Mars rules it, but Mars operating through water rather than fire: force applied indirectly and with patience. The Moon is debilitated here, which is the classical statement that a mind in this medium finds calm hard to come by.
