Battlefield medics have a very rough job (putting it mildly). Everyone out there is looking to tear each-other to shreds. They're looking to put people back together again. Solar Auxilia Surgeon-Primus Aevos Jovan was a great surgeon before some of his "experiments" were discovered and he was given the option of cake or death... I mean, working for the Solar Auxilia or death. He chose to work with the Solar Auxilia.
Solar Auxilia Surgeon-Primus Aevos Jovan and his orderlies are part of the Horus Heresy Character set of figures. You get the good doctor, himself, along with a pair of orderlies. Along with that, you get his auto-gurney, complete with patient (and recently-amputated leg bit). The set is available to order now, with those orders being sent out next week.
