Oya is Shango's favorite wife, b/c she keeps him calm, and tempered his anger against the people of Oyo. It is for this reason that some people say that Oya and Oshun donot get along, and consequently, that Oya people and Oshun people won't get along, but that is not necessarily true...

>oshun--http://en.wikipedia.org/wiki/Osun
>In Yoruba mythology, Oshun (or Oschun) is a spirit-goddess
>(Orisha) who reigns over love, intimacy, beauty, wealth and
>diplomacy. She is worshipped also in Brazilian Candomblé Ketu,
>with the name spelled Oxum.

>Oshun is beneficient and generous, and very kind. She does,
>however, have a horrific temper, though it is difficult to
>anger her. She is married to Shango, the sky god, and is his
>favorite wife because of her excellent cooking skills. One of
>his other wives, Oba, was her rival. They are the goddesses of
>the Oshun and Oba rivers, which meet in a turbulent place with
>difficult rapids; their rivalry was symbolized in this
>intersection.
