This is a list of fictional characters featured in the Known Space novels by Larry Niven. Individual characters Sigmund Ausfaller Sigmund Ausfaller, a native of Earth, is a member of the Amalgamated Regional Militia ("ARM"), working in the Bureau of Alien Affairs on Earth. To protect puppeteer (and Earth) interests, in "Neutron Star" Ausfaller plants a bomb in the lifesystem of Shaeffer's ship, the Skydiver, so that Shaeffer will not attempt to steal it. Years later, in The Borderlands of Sol, when Shaeffer encounters him on Jinx, he offers Shaeffer and Carlos Wu a ride home to Earth on his ship, Hobo Kelly, in hopes of attracting the attention of whoever or whatever was causing ships to disappear when entering or leaving Sol system. Some years later, Ausfaller, having almost caught up with Shaeffer on Fafnir, is killed by Ander Smittarasheed in order to protect Smittarasheed's interest in the special nanotechnology autodoc developed by Carlos Wu, left on Fafnir when Carlos escaped from Feather Filip as she shot Shaeffer in the chest with an ARM punchgun. He is later "resurrected" by Wu's Autodoc and taken to one of the Puppeteer farming worlds by Nessus. Ausfaller appears in the Beowulf Shaeffer stories "Neutron Star", The Borderland of Sol, and "Ghost", and is mentioned in the story "Procrustes". He also appears in the non-Shaeffer novel Fleet of Worlds and is the main human character in its sequels Juggler of Worlds and Destroyer of Worlds.

He is 300 years old and takes boosterspice, although he was born before that drug became available; initially, like all humans before boosterspice, he relied on the organ banks to keep him healthy. An outgoing, interesting man, Bellamy talks well; he tells old jokes but does it well, and he has some new ones, too. While not xenophobic, Bellamy tends to not think of aliens as people; Shaeffer remembers that he had said they should wipe out the Kzinti for good and all. Bellamy is the leader of a hunting party visiting Gummidgy when the Kdatlyno touch-sculptor Lloobee is kidnapped. When Shaeffer discovers that Bellamy is part of the kidnap plot, he and Emil
