-\paragraph{Marching} inflicts \pglspl{fatigue} each mile of rough terrain, such as wild forest, or mountains, and half that when walking on a road (meaning 1 \gls{fatigue} every 2 miles).
-Since characters recover half their \glspl{fatigue} over \pgls{interval} of rest, a character with 8 \glspl{hp} could march 4 miles in the morning, recover 4 \glspl{fatigue} over an afternoon's rest, and repeat that over the evening and night.
-That leaves characters marching a number of miles equal to their \glspl{hp} each day, without accruing \glspl{fatigue}, or double their \glspl{hp} when walking on a road.

 \paragraph{Poison} can become a nasty drag on a character, and a serious poisoning can prompt even the strongest fighter to go find a cure, before he vomits any more blood.
 
 \paragraph{Starvation} is another special case.
-\glspl{fatigue} inflicted from starvation are marked with an `$S$', and each of these points only heal once the character has had a full meal.

-\Glspl{npc} should acrue \glspl{fatigue}, just like the \glspl{pc} do.
-The \gls{gm} might assume \glspl{npc} have a number of \glspl{fatigue} equal to half their \glspl{hp} at any time, unless the situation suggests otherwise.

 Players should be able to use this to their advantage, just as their \glspl{pc}' tired bodies work to their disadvantage.
