A quest is a journey toward a specific mission or a goal. It serves as a plot device in mythology and fiction: a difficult journey towards a goal, often symbolic or allegorical. Tales of quests figure prominently in the folklore of every nation and ethnic culture. In literature, the object of a quest requires great exertion on the part of the hero, who must overcome many obstacles, typically including much travel. The aspect of travel allows the storyteller to showcase exotic locations and cultures (an objective of the narrative, not of the character). The object of a quest may also have supernatural properties, often leading the protagonist into other worlds and dimensions. The moral of a quest tale often centers on the changed character of the hero.

Reality is a concept that varies with context and culture. Reality may be viewed as the sum or aggregate of all objects in existence within the universe, as opposed to that which is only imaginary, nonexistent or nonactual. The term is also used to refer to the ontological status of things, indicating their existence. In physical terms, reality is the totality of a system, known and unknown.

Philosophical questions about the nature of reality or existence or being are considered under the rubric of ontology, which is a major branch of metaphysics in the Western philosophical tradition. Ontological questions also feature in diverse branches of philosophy, including the philosophy of science, of religion, of mathematics, and philosophical logic. These include questions about whether only physical objects are real (i.e., physicalism), whether reality is fundamentally immaterial (e.g. idealism), whether hypothetical unobservable entities posited by scientific theories exist, whether a god or gods exist, whether numbers and other abstract objects exist, and whether possible worlds exist. Epistemology is concerned with what can be known or inferred as likely and how, whereby in the modern world emphasis is put on reason, empirical evidence and science as sources and methods to determine or investigate reality.
