Speed of sound with a white dragon

I did mean threaten in the game mechanics sense, but that may or may not be valid for contingency; the spell is hideously vague that way.

Thrown anything doesn't threaten (ranged attacks), mud pies wouldn't threaten (not a weapon), etc.

Well now we're talking about metaphysical gaming constructs. Your wizard doesn't know what those are~!
