Roche Sabins, Rogisabens, Roisawenz
The capital city of the land ruled by King Gramoflanz, Gawain’s enemy. It had previously been owned by Gramoflanz’s father, King Irot.
The town was well-guarded with numerous moats and towers. It stood near the sea, between the Sabins and Poynzaclins rivers. Near Roche Sabins were Joflanze, a dueling ground.
Sir Tandareis were imprisoned, but were helped to attend tournaments at Sabine, which might be Roche Sabins.
