Senwannus'gourkahipaff
known as Sen for short, this huge Oswaft was the senior Elder in the Oswaft society when Lando Calrissian first met Lehesu, during the early years of the New Order. Sen measured just over 1,000 meters in width, making him the largest Oswaft in the ThonBoka. During the Imperial blockade of the ThonBoka, he played sabacc with Lando as Lando outlined a plan to break the blockade. Being somewhat more forward-thinking than his counterparts, Sen agreed with Lando's plan to fight back without violence, and helped break the blockade in the end. Sen then asked Lehesu to become one of the rulers of the Oswaft society, fearing that his conservative nature almost cost them their lives. The apostrophe in his name represented twelve other syllables in his name, which he was too modest to use. During the defense of the ThonBoka, Sen was among a group of Oswaft who were caught by the first blast from the Wennis, which fired some of the deadly bio-engineered weapon that had been developed by Rokur Gepta. Sen and his comrades were killed in the blast.
