This archway seems to be the only way of getting past the huge wall
surrounding the city of Decara.  You can see a wide street running to the
west, but a large ogre guard stands in your way.  To the east is a
drawbridge leading across the river and out of the city, and to the north
and south are doorways that have been carved out of the wall itself.
