Cavities provide a promising avenue to achieve long-range interaction by enhancing the coupling of remote qubits through shared cavity modes. In this work, we investigate a spin array coupled to a ring cavity supporting two counterpropagating modes, focusing on the system's eigenstates and spin dynamics in the low-excitation regime. We show that, under specific spatial configurations, the spins naturally self-organize into two groups, within which exciton transport is confined.
