You are at the Castle gates.  Guards check out the area making sure it is
secure.  They look you over curiously.  The high stone walls ahead provide
sturdy protection from invaders.  The gate is made up of many iron bars that
extend at least 20 feet high.  You glance around as the gate is being
lifted, in suspense at getting inside the castle to take care of your
business.
The gatekeeper is here, running the gates.
