Hester Aspertia Sigma-Sigma

Chaos Portal Dark Mechanicum

Hester Aspertia Sigma-Sigma was a Magos Domina of the Mechanicum during the Great Crusade and Horus Heresy. She was known as a master of cloning and soul-merging.^[2]

Initially a loyalist of the Emperor, when the Sons of Horus led by Horus himself attacked her world of Trisolian A4, she quickly defected out of fear that her collective knowledge, including her plans to become immortal through cloning, would be lost. After siding with Horus she disgusted her acolyte Belisarius Cawl, who killed her during the Battle of Trisolian. Cawl destroyed her fetal clones, but downloaded her collective knowledge into himself.^[1]
