"The rifle scans in the infrared, which shows heat given off by creatures. The point was twofold." Lyra explains, seemingly not caring about the laughing. "Firstly, if the imp gave off heat I could quickly take it down with a nice simple shot, and have us home by lunch. Since he didn't show up, I can now tell Marcus where all the creatures who did show up on infrared are," so saying she leans closer to Marcus and points out the location of the small forest creatures, who taps on his own bracer which was hidden by a hoodie sleeve, "And he can set his smart discs to ignore those creatures movements. Now, he releases one of the smartdiscs, and it'll go after any movement that isn't marked as nontarget." Marcus opens his coat, revealing 3 smart discs and a small revolver, and releases one, which hovers in the air for a short bit as it scans with a noise identical to a colonial marines motion detector.
