Herv Gresham

 was an official on Kassagrad. According to Bernice Summerfield he was a very polite man. He helped Luci Yendipp when she arrived on the planet to find Daglan Straklant. He told Benny about the defence shield around the planet, and that was why the Fifth Axis hadn't invaded. He used the codes that Irving Braxiatel managed to get from Daglan to make the Axis withdraw.
