ω Cen is unique among the Galactic globular clusters. It exhibits not only classical mixing signatures, but also those of primordial chemical enrichment by both massive and intermediate-mass stars: the abundances of all elements vary, not just those of the C, N, O, Na, Mg, and Al. The challenge is to disentangle the roles of mixing and primordial phenomena. We discuss here what sets ω Cen apart from the other clusters.
