Cecilia Detweiler was a member of the Mesan Alignment and its ruling Detweiler family. She was a great-great-great-granddaughter of Leonard Detweiler. She once surmised the Alignment's plan for destabilizing the Solarian League by saying, "We will bring down the great bison with a pack of wolves. The tricky part is that we don’t control the wolves." (CS3)
