Zwei, the eldest of the J'sibs. Possibly the craziest... Though that can be disputed by the elder J'triplets.

Zwei was a member of the Red Quill before she decided to head back to the Mainland in search of more ingredients for her infamous soup. Only Polgara and ToriAnn know where the rest of her soup is buried on the Lok'Groton island chain.
