The Rachind is a stick insect -like alien who is one of seven contestants in the seventh Presidian in Contest.
Rachnids are an alien described as resembling a stick insect. They are trap-layers, waiting on the ceiling of caves before they jump down to strangle its prey with its eight strong, spider-like legs.
When the Presidian starts up, Rachnid and the six other contestants are teleported into the New York Public Library. Rachnid made it to be the fourth contestant left and attempted to kill Bellos when he was about to kill Holly Swain and Selexin. While Rachnid fought Bellos, Holly and Selexin flee and later witness Rachnid's death at the hands of Bellos and his Hoodaya.
