Bram is a protector who controlled the Ringworld control center throughout the events surrounding Ringworld (novel), Ringworld Engineers (novel), and Ringworld Throne (novel).

Bram was originally of the Vampire species, and was only sentient after having made the transition to protector. This likely means that he is of significantly lower intelligence than a protector risen from a species that is already sentient.[1]
