  I address the phenomenology of CPT violation in the neutral kaon system under
the assumption that it originates from Planck scale physics. This assumption
opens the door to a new set of CPT violating parameters whose phenomenology is
distinct from the $\Delta$ parameter usually considered in the Hamiltonian. The
origin of these parameters reflects a possible departure from a $S$-matrix
evolution. Existing bounds on CPT violation are near the expected range based
on naive dimensional analysis. This provides a strong incentive to pursue the
quest of CPT violation in near-future kaon experiments. (Talk given at the
Workshop on K Physics, Orsay, France, May 30 - June 4, 1996.)
