The Dead Giants

This large "forest" is composed of the husks of hundreds and thousands of giant tube worms. Some of the tubes have been shattered and toppled, but most remain upright. The worms themselves are no more, and none knows the exact nature of their fate. They may have been hunted to extinction, or perhaps were the victim of some malicious plague. Regardless, their shells remain, and have become havens for all types of sea creatures, intelligent and otherwise.
