Lau is a trader from the island of Two Moons and one of its Council members.
Lau, Xen and Bool went out to greet the Star of Deltora and its crew when they had gotten off the ship. They appeared to be in a rush however, as both her and the others had sloppily put on their attire. Lau commented to Mab that she was surprised to see her out of season, but nodded and smiled at Mab's compliment of Two Moons' traders, after explaining her situation. After Xen explained the swamp dwellers warning, Lau declared that the Council should have put the savages in their place long ago. She continued, criticising their ego and part swamp dwellers, warning against allowing them to dictate. She stood on end after Mab hoped that the old Two Moons trick of new traders being drugged and robbed of their purchases be suspended.
Like her other Council members, Lau wore bright coloured robes that reached to ground and a bright turban made of yellow silk. When the Star of Deltora landed at Two Moons' port, she was wearing odd coloured shoes, the left was black and the right, dark blue.
Lau regarded swamp dwellers as savages and disliked the power they had over the other residents of Two Moons. She also disliked half swamp dwellers in the same way.
