Caha (unknown – 1503) was a member of the Templar Order and a French noblewoman, who dressed in the costume of a hellequin. She was the sister of Cahin, the Harlequin, and an individual in the service of Cesare Borgia. In 2012, her genetic memories were used as an Animi Avatar by the Templar company Abstergo Industries, in the first stage of training for their Animus recruits, under the title of the Hellequin.
