You are standing on the end of a narrow granite bridge which overlooks
Rune River.  Beneath you is a fast flowing stretch of the river, carrying
fallen branches and debris downstream.  Leaves from the trees which line the
river bank drift gently downwards and some are carried away with the wind. 
In the water you see a few shifting colors and realize it is fish fighting
their way upstream but seeming to stay in the same spot.  Several of the
fish are fairly large and would make an excellent dinner.
