Kirilow was the mother of three females (Vaxa, Reayi, Teaxixa) and one male (Astradem). She was married to Alacem Ukinix (nee Sada). Madly in love with each other, together they were known by the other houses as ruthless and cunning heads of the Ninth House.
Kirilow and Alacem deliberately pitted their children against each other to determine the best suitor of the title of head of the House, even though Vaxa was the eldest daughter and Matriarch Ascendant.
