Literally "God in the machine", Deus Ex Machina originally referred to Greek plays, where the "gods" would be lowered onto the stage with ropes in order to provide a quick resolution to the story. Today, Deus Ex Machina refers to any improbably and/or overly convenient character or mechanism that comes out of nowhere and saves the character(s).
