V�r is one of the �synjur according to the Prose Edda.
The tenth is V�r: she is wise and of searching spirit, so that none can conceal anything from her; it is a saying, that a woman becomes 'ware' of that of which she is informed."
Apart from this pithy quote the goddess is essentially unknown
Sj�fn(not Vjofn) is one of the �synjur in Norse mythology.
The seventh [of the �synjur] is Sj�fn. She endeavours to turn the minds of people to love, both those of women and men, and from her name a lover is called sjafni."
The name Sj�fn is not mentioned again in the Prose Edda and occurs nowhere in the Poetic Edda. It does occur a few times in kennings as a generic goddess name (e.g. Sj�fn seims means "Sj�fn of gold", i.e. "woman"). It is unclear whether Sj�fn was ever a major goddess. It is possible that, unknown to Snorri, she was simply another name for Freyja.
