Time available for recovery
A bit of research. Observing when buried items can no longer be recovered in certain regions. (Using Ankh-Morpork pennies.)
Assuming: Disappear time is the same for a single type of item, disappear time in an area is fixed
|Location||Longer than||Shorter than|
|Cabbage fields outside Ankh-Morpork||6 minutes, 20 seconds||6 minutes, 31 seconds|
|Losing Street, Ankh-Morpork||7 minutes||8 minutes, 1 second|
|Main Hall of the Thieves' Guild||7 minutes||7 minutes, 21 seconds|
|Muddy part of the river Ankh||6 minutes, 15 seconds||7 minutes|
|Solid part of the river Ankh||7 minutes, 3 seconds||7 minutes, 30 seconds|
When it is completely dark you cannot examine any items, and you cannot bury them:
> bright Wherever you are, it's in pitch darkness. > drop penny You drop something. > look at penny It is way too dark to see anything at all. > bury all Cannot find "all", no match. > bury penny You cannot see well enough to bury anything. > get penny You get one Ankh-Morpork penny from something.
When it is bright enough to determine the presence of an item it can be buried:
> bright Something is in near darkness. > drop penny You drop something. > look at penny some coins > bury all Cannot find "all", no match. > bury penny You tidy up the place, clearing away something. recover penny You recover one Ankh-Morpork penny.
