At a glance, Yako can't tell how old 'Toby Hamee' is or whether they're a boy or girl, but that's all pretty irrelevant to the matter at hand -- someone needs help dealing with a relatively practical problem. ]

Hm ... maybe it would make sense to start looking in places where people deal with dangerous equipment every day? Like a carpenter's workshop or a forge. I haven't heard of any spells like that myself, but if they're working with tools like that every day, I'm sure they must know a thing or two about preventing accidents.
