Sweeping the Elder Wand, I knew what to cast. "Mortuus Revelio." My vision swam with dead bodies all around me, but I was able to filter it all out. I spread my senses out and found the one blip in my senses that scrambled with fear, moved with that unnatural quickness the dead should never have, and knew it was the Inferi I was looking for. It moved too fast, and it was definitely trying to get somewhere. It just seemed... brighter, as if the Goblin took more of an effort to reanimate this one.
