THE FERMI MISSION HAS ENHANCED MAGNETAR SCIENCE THROUGH THE OBSERVATION OF PROLIFIC FLARE ACTIVITY FROM SELECT SOURCES USING THE GAMMA-RAY BURST MONITOR. MAGNETAR SPECTRA ARE OFTEN BEST FIT BY A POWER LAW WITH AN EXPONENTIAL CUTOFF A SO-CALLED COMPTONIZED FORM. THIS PROPOSAL IS TO PERFORM DETAILED RADIATIVE TRANSFER IN AN ELECTRON-PHOTON CLOUD MODELING THE ESTABLISHMENT OF MAGNETAR SOFT GAMMA-RAY SPECTRA USING A MONTE CARLO APPROACH. THE HIGH THOMSON OPACITY IN THEIR MAGNETOSPHERES YIELDS POLARIZATION-DEPENDENT ANISOTROPIC COMPTONIZATION. GIVEN AN IMPULSIVE INJECTION OF ENERGY AT EITHER EQUATORIAL OR POLAR LOCALES THE TRANSPORT OF RADIATION AND ENERGY EXCHANGE BETWEEN PAIRS AND PHOTONS WILL BE TRACKED USING FERMI-GBMOBSERVATIONS TO PROVIDE DIAGNOSTICS ON THE INJECTION SITE.
