One day, a giant lay down his head, in a marshy field, and took his final rest.
One day a snail left its bed, in search of a new place to dream
The snail crawled inside the giant's rotting skull, and began to dream new dreams. It dreamed that it was king of all the giants. It dreamed of things beyond what it had ever known. It dreamed, and its visions crawled out and manifested into oozing forms, a golden crown reaching towards the sky, fitting a giant king. Its dream stretched into new realities, infinite and strange, and this dream could not be denied.
The slumbering monster saw the world for the first time
The phalanx of dreaming shells is a giant creature that can appear at dawn or dusk, at any beach or marshland. Its base is the rotting head of a giant, but it is covered in different people, creatures and things, that have gotten in its path, and thus become a part of the dream. It is generally stationary while in its corporal form, but it IS able to slowly crawl on the roots and legs of the collective dream, and has been seen doing so. There is a legend that once it manifested in a town center, and the entire city was swallowed up into the collective dream, and never seen again. But nobody remembers the city's name, or where or when this city existed.
If you touch the Phalanx, there is a chance that you may become attached, and swallowed into the dream forever.
The Phalanx can be entered through the mouth, and once inside adventurers can encounter one of the many different worlds and creatures that inhabit the different dreams. Just be sure not to stay for too long, lest you also start to dream.
I'll be posting about different inhabitants of the dream in future posts :)
