There are said to have been eleven original centaurs. All eleven are children of one human and one quadraped parent. Bitter theological debate rages over whether they came from human fathers and animal mothers, or vice versa. An alternative theory holds that centaurs were created by a twelve year old sorceress, after her friends could not decide whether boys were better than horses.
They were "as strong as the towers of Bel-Narana; as light as those gossamer palaces that the fairy-spider builds 'twixt heaven and sea along the coasts of Zith; as swift as a bird racing up from the morning to sing in some city's spires before daylight comes."
There were five male and female couples, one each for the five types of centaur.
The eleventh, and youngest, was Ianidhini, who was brought forth to keep peace between the other ten. He or she is both male and female, so as to understand both, and at other times of no gender, to be fooled by either. For similar reasons, Ianidhini's hindquarters are a mixture of all the five types of centaurs.
Ianidhini is the only one of the eleven who is much worshipped other than by centaurs. In Teleleli Ianidhini is the god and goddess of worldly wisdom, and of all who dress in the clothes of the opposite gender, whether for reasons of disguise, acting, or inclination.
The nameless God of Unfinished Things is also a centaur, although he is not worshipped by centaurs.
