  New superstrong forces, analogous to QCD but featuring a larger mass scale,
should they exist, would offer new possibilities for addressing the strong P,
T, problem. One can implement the "massless quark" solution in a
phenomenologically acceptable way, by using a massless quark that is always
confined within superheavy particles, and is therefore effectively superheavy:
a cryptoquark. Assuming confinement and chiral symmetry breaking from the
superstrong dynamics, we find a new mechanism to generate an axion field
without introducing new fundamental scalar fields.
