The bridge to Caras Galadon(n and s)

You are now almost at the gates of Caras Galadon. Many have sought to find this mystical place, and many have failed. As you look northward towards the gates, you see for the first time why so many have tried. The walls of the city seem almost to shimmer, and dazzle your eyes with their pure white color. The water is the dirtiest you have ever seen, as it roars underneath this beautiful structure. Staring at the water, you notice that many branches and debris are being swept along with the current. There is no way that the elves would do such a thing to this wonderful place. You sigh, and watch the muddy water lick at the base of the walls.
The only obvious exits are north and south.
