Umbrennial

Umbrennials are plants that project shadows out into the world by unknown mechanism. Different varieties of umbrennials exist, varying in size, shape, and the shape, size, or number of shadows produced. The smallest umbrennials are the size of a glass, creating a single shadow only large enough to hide a marble. Other umbrennials can become towering tree-like structures that cloak wide swathes of land. The largest recorded umbrennial lives in a fornifera plain, where it is said that one must take days to pass safely by it.
