It's probably for the best that Firo has no idea how to detect something like that. No matter how obedient a familiar is, just the thought of some other being quietly hanging around would creep him out. He nods at Hector's answer, trying to imagine what an actual familiar would look like. Probably weird. "So probably more dangerous than a black cat."

He raises an eyebrow as he watches Hector reveal the blades. Having no experience in forging or carving, he's impressed even with the wooden ones. "You made all a' those?"
