It was a flurry of questions, though Kaiya did his best to avoid feeling overwhelmed, and started with what he felt to be the most important one.
"It is a practice that does not involve the kami, and indeed many of those caught cannot speak to the elements at all. I know distressingly few specifics about it all, but for very good reason; there are only evil spirits involved, and only evil can be done with it, as the bloodspeaker himself did in his attempt to destroy the Empire not even a decade past. As such, I only have speculations on why Iuchi Tareef would be the creature's first target."
"As for this sand.. I would not touch it myself, but I believe it should be something that the eta can clear with some care. If it were my decision, it would be gathered into a sturdy container, possibly even studded with jade, and given to the Crab to properly dispose of."
That he imagined such 'disposal' to involve an urn full of the stuff launched over the Wall by catapult was a little silly to voice, however.
