The inner galaxy provides a unique environment to study both interstellar medium processes in extreme states and the conditions of active galactic nuclei. The central 200pc of the Milky Way shows high densities, radiation field, cosmic ray fluxes as well as strong magnetic fields. These effects may explain the high rate and special characteristics of galactic center star formation. Energetic events originating in the vicinity of the central black hole shapes the kinematics and structure, especially out of the plane. Several new data sets and observatories have recently given improved insights into the gas, dust, and magnetic field, including SOFIA, ALMA, and MeerKat observations. We will be having a Special Session to explore this new data on the exciting characteristics of the extreme ISM in the central 200 pc.
