These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.

The "fifty-foot columns of flame" thing isn't much of an exaggeration, and it can be pretty frightening the first couple of times if you don't know it's coming.
