  We study the problem of integrating an invisible axion into the
Randall-Sundrum scenario as an example of how to generate new energy scales
between the extremes of the Planck mass and the electroweak scale. In this
scenario, the axion corresponds to the phase of complex bulk scalar field. We
show how to generate an intermediate energy scale by including a third brane in
the scenario. We discuss the stabilization of this brane in detail to
demonstrate that no additional fine-tunings arise.
