The biconical radiation pattern extending from an active galactic nucleus(AGN) may strongly photoionize the circumnuclear interstellar medium (ISM) andstimulate emission from the narrow line region (NLR). Observations of the NLRmay provide clues to the structure of dense material that preferentiallyobscures the bicone at certain angles, and may reveal the presence of processesin the ISM tied to AGN accretion and feedback. Ground-based integral fieldunits (IFUs) may study these processes via well-understood forbidden diagnosticlines such as [O III] and [S II], but scales of $\sim10$s of pc remainchallenging to spatially resolve at these wavelengths for all but the nearestAGN. We present recent narrow filter Hubble Space Telescope (HST) observationsof diagnostic forbidden ([O III], [S II]) and Balmer (H$\alpha$, H$\beta$)lines in the NLR of IC 5063. This AGN's jet inclination into the plane of thegalaxy provides an important laboratory for strong AGN-host interactions. Wefind evidence for a low-ionization loop which emits brightly in [S II] and [NII], and which may arise from plume-like hot outflows that ablate ISM from thegalactic plane before escaping laterally. We also present spatially resolvedBaldwin-Phillips-Terlevich diagnostic maps of the IC 5063 NLR. These mapssuggest a sharp transition to lower-ionization states outside the jet path, andthat such emission is dominated by $\sim10-40$ pc clumps and filamentarystructure at large (>>25{\deg}) angles from the bicone axis. Such emission mayarise from precursorless shocks when AGN outflows impact low-density hot plasmain the cross-cone.
