Not sure if he really expected us to pass on proper warnings or not.
Outside the temple Ikki and I went into, there was a wooden altar that didn't seem quite as damaged as it should've been. And a jackalope taunting us. Looked like someone else might've checked the place recently, though, so there's a chance whatever was there is gone now.
The building Link and Tide checked... ah, they were seeing things in it, might've also been Horn's doing but that's worth a recheck by another group, too, just to be sure it was taunting and not active misdirection.
