AGN outflows are widely invoked as the key mediators between the co-evolution of black holes and their host galaxies. Yet, the key question remains: do the outflows actually deliver enough power to their environments to alter evolution in a meaningful way? To address this, we present results from a new 440-ks Chandra HETG GTO observation of the kpc-scale ionization cone in the canonical Seyfert 2 galaxy NGC 1068. We perform the first spatially resolved, sub-arcsecond scale, high-resolution X-ray spectroscopy of an AGN environment, and use the sensitive line diagnostics offered by the HETG to measure the outflow rate, ionization state, density, and temperature at discrete points along the ionized NLR. We investigate evidence for any velocity gradients in the outflow, and describe our next steps in modeling the NLR as a multiphase biconical outflow. Our results have key implications for the role of galactic-scale outflows in AGN as moderators of galaxy evolution.
