Claudius looks at the little wrapped charm with some surprise, though it takes some time to untangle why -- alchemical reactions of various kinds can create sparks to for flare, and that's without the subtler magics Lan Wangji knows. He's curious how it works, but not doubtful of the claim that Lan Wangji will come wherever it's used. It surprises Claudius how such a gesture can still humble him. "Quite a significant gift," he says, and closes his hand around it. "I'll hold it close. And perhaps ... I ought to warn you, if I believe I may be courting danger. I'd hate to catch you at an inopportune moment." The last, he says with a flickering smile.
