Consider Phlebas, first published in 1987, is a space opera novel by Scottish writer Iain M. Banks. It is the first in a series of novels about an interstellar post-scarcity society called the Culture. The novel revolves around the Idiran–Culture War, and Banks plays on that theme by presenting various microcosms of that conflict. Its protagonist Bora Horza Gobuchul is an enemy of the Culture.
