About the most benign consequence of this I can imagine would be the line of inquiry being snuffed out, and a major magical accident in K8P, even flushed by the room of calamity, making some waves.
With the attention roll, I feel like a 5-10 range is pretty likely to be aspected to each of the chaos gods, since it includes each of their numbers, so the result of 9 would then imply Tzeentch taking an interest. Could just move the miscast roll up a table, or could be something else whacky and probably awful.
