  An electron-proton/ion polarized beam collider (EPIC) with high luminosity
and center-of-mass energy $\sqrt s = 25$ GeV would be a valuable facility for
fundamental studies of proton and nuclear structure and tests of quantum
chromodynamics, I review a sample of prospective EPIC topics, particularly
semi-exclusive reactions, studies of the proton fragmentation region, heavy
quark electroproduction, and a new probe of odderon/pomeron interference.
