Sennar was a town in the Empire of Kar V'Shem. The laughing waters of the River Veprel flowed through the town. It was here that the knight Rand fell in love with Dianora, the wife of local merchant Ansovald, and was able to convince the wizard Portolis to create a garden that bloomed in the winter.
