Here’s some of the relevant code:
The Yesod Key is a key. The Yesod Key is hidden in Chamber of Creatures. The description of the Yesod Key is “The Yesod Key is vitality for Galmi’s pelvis.”
Lighting it with is an action applying to two things.
Understand “light [something] with [something]” as lighting it with.
Check lighting it with:
if the player does not hold the second noun:
say “You’re not holding [the second noun].” instead.
Check lighting it with:
if noun is lit:
say “That torch is already lit. Try looking at the chamber to see what may now be visible.” instead.
Report lighting an unlit torch with a lit torch:
now the noun is lit;
say “You light [the noun] with [the second noun]. Now you can see some things in the chamber you couldn’t see before. Maybe you should look at the chamber again.”.
Every turn when there is a lit torch in the location and there is a hidden thing (called an item) in the location:
say “Something sparkles in the light. It looks like [an item].”;
now the item is revealed.
