Immediately, she felt a strange vibration. Vin paused. The pulses didn’t make a sound that she could hear, yet she could feel them washing across her. They seemed to be coming from Kelsier. She looked at him, frowning.
“That’s probably bronze,” Kelsier said. “The internal mental Pulling metal. It lets you sense when someone is using Allomancy nearby. Seekers, like my brother, use it. Generally it’s not that useful—unless you happen to be a Steel Inquisitor searching for skaa Mistings.”
Vin paled. “Inquisitors can use Allomancy?”
Kelsier nodded. “They’re all Seekers—I’m not sure if that’s because Seekers are chosen to become Inquisitors, or if the process of becoming an Inquisitor grants the power. Either way, since their main duties are to find half-breed children and noblemen who use Allomancy improperly, it’s a useful skill for them to have. Unfortunately, ‘useful’ for them means ‘rather annoying’ for us.”
