The Omega stood for many things in the ancient Greek world. It was a letter, syllable, and a representation of the number 800. It is also the namesake of the Omega Centauri globular cluster. Mathematically, it is the maximum limit to a set. It is most importantly known as the representation of the end or last. It was found on some ancient Spartan shields as a warning to their enemies that the 'end was near'. In modern times, it has been popularized by the video game God of War, in which it is a symbol of the war god Ares. Omegas, in social terms, are outsiders, notable for distinction and do not conform to existing peer hierarchies.
