The Thoughtless Colossus is an immense mycomantic amalgam-form. A shambling fusion of flesh, bone, and fungus, the Thoughtless Colossus is all that remains of the Spine city-state of Bayokai, which was transformed into the Colossus in the later years of the ninety-eighth century.
The Thoughtless Colossus has no fixed form, but rather stretches and contorts itself as needed. At rest it typically retracts into a relatively compact mass, a mound roughly fifty to eighty feet high, while in motion it elongates into a more slug-like form. As a living entity, the Colossus requires food and water, which it consumes through countless mouths that can be found across its surface. It is undiscriminating in what it eats, largely subsisting on whatever plant and animal life is unfortunate enough to be caught in its path.
Though evidently incapable of any means of coherent communication - setting aside the ceaseless moans, gasps, and wheezes from its thousands of mouths - the Thoughtless Colossus possesses at least some intelligence, as those who have unwisely tried to destroy it have learned. It remembers people, places, and objects of particular threat or nutrition to itself and avoids or returns to these based on past experiences. While the Colossus seems to have a distaste for saltwater, it is capable of swimming and surviving in it, and as such passes between the islands of the Shatter with some regularity.
