Mother of the gods, guardian of women
During the time when Roland was Prime Minister of a realm in the Outside, he met, courted, rescued and eventually married Sian, Duchess of House Celestine. When he created Aurellis, he invited Sian to become his partner as a deity, and she accepted, taking charge of the part of Aurellis which she determined he was least able, namely the feminine.
Sian realised that the contrasts of Roland’s beliefs regarding the nature of sexuality and marriage would place an intolerable burden upon women, unless she acted to prevent this. Therefore, she granted to all females who wished to accept it, her blessing, such that the female may never conceive of an unwanted child. In fact, unless a woman who has received this blessing takes her chosen male before a priestess of Sian to affirm that her choice to conceive with that man is free and true, or undertakes an elaborate ritual to Sian, then no conception will happen. Thus can women partake freely in the sexuality which men take for granted. Sian will not condemn any women for her choice of partner, and will accept any unions, even those that are condemned by others as criminal.
Sian accepts only women as priestesses, and only women may serve in her Temples. It is generally assumed that Sian is bisexual, as some of the rituals of her temples are sexual in nature, with resulting effects that appear sorcerous in nature.
