The Ringworld Throne is a science fiction novel by American writer Larry Niven, first published in 1996.

He wrote it as a replacement after being unable to finish his contracted novel The Ghost Ships, the sequel to The Integral Trees and The Smoke Ring.

With the help of two Ghouls, who know that the nest is located under an abandoned floating factory, they manage to cast out the vampires.

After ten years of wandering around the Ringworld and aging, the Hindmost convinces him that he killed far fewer people than expected.

Bram shoots down ARM and Patriarchy ships attacking the Ringworld, and then tries to overthrow the other vampire Protectors who control the rim wall.
