Who is Bayta from Foundation and Empire and what is their importance?

Bayta is a newlywed and member of the Foundation, Bayta is enmeshed into the battle though her marriage to her husband, Toran. She's pretty though Toran says that it's in an ordinary sort of way. Her dark hair, pale skin and confident bearing earn her second looks and respect wherever they travel. On one planet, Bayta takes her place with the men and even smokes a cigar - an action that the planet's people think is incredible but they do accept that she's confident enough to take her place among the men.
