Shaped like the letter 'S', the branch makes an odd turn.  Below you, the
canopy of the smaller trees is thicker than ever, and the sky seems to have
disappeared behind this tree's higher branches.  Going any further on this
branch could prove fatal, but there's always a chance that it won't.  The
branch leads back the way you came to the east, and the end of the branch is
to the south.
