"Sire," said the Minister of the Interior to Napoleon, "yesterday I saw the most intrepid man in your Empire." - "What man is that?" said the Emperor brusquely, "and what has he done?" - "He wants to do something, Sire." - "What is it?" - "To visit the sewers of Paris."
The Sewer Beneath St Denis is a room. "A narrow, stone-lined passageway, with only a little ledge to walk above the level of the refuse that flows down towards the Seine."
The candle is carried by the player. The description of the candle is "A candle, [if the candle has been lit]partially burnt[otherwise]still in pristine condition with untouched wick[end if]."
Instead of examining the lit candle, say "It burns with a pure heart."
The block burning rule is not listed in the check burning rules.
Instead of burning the lit candle:
say "The candle is already lit."
Check burning:
if the noun is not the candle, say "[The noun] cannot profitably be set on fire."
We must be careful: "if the noun was lit" would throw errors because past-tense rules can only be applied to specific items, not to variables that could be anything.
