What kind of safes do you know that are quick to open in an emergency? [He holds up a hand, like, this isn't criticism,] I'm honestly curious; that would save us oodles of time.

[Oodles of it. On his raised hand he counts off effects on his fingers:]

One, corruption; two, spiritual; three, unknown. Two of these are easy enough to write off, I obviously can't explain unknown effect but I wouldn't rule it out, and as for spiritual— maybe it's haunted. Not every ghost is willing to talk to me, so my tricks to coax them out aren't foolproof.

[He moves to tap on the glass, as if he could wake any potential ghosts in there, and continues,] As for the first, corruption is still steeped in enough mystery to make me worry. We treat it like a metaphor, based entirely in the mind, but I'm not convinced. I think it might become a real force once generated, and it needs somewhere to go, something to hold onto it when it's pushed away from something else. I've seen corrupted stones— they're visibly changed from their original form. The theory is sound, and so... well, I wouldn't want you to put on an evil scarf.
