The weak areas in the Transformation Dust Layer Flow were observed indirectly; in fact, no one had actually penetrated the entire layer.
It began with the observatory at the Starlight Torch Tower, which detected a star deviating from its previously mapped trajectory. At the same time, dimmer stars were discovered around it for the first time.
Some scholars attributed this phenomenon to a change in the star itself, such as a split, which would explain both observations. Others, however, raised doubts, pointing out that the split-star hypothesis couldn't explain why the original star had actually grown brighter.
There were even historical researchers who pointed out that ancient texts and star charts had recorded the existence of those celestial bodies.
