Origin

Johannes Fabricius was a Frisian astronomer who discovered the existence of sunspots independently of more famed counterpart Galileo Galilei. To avoid direct observation and eye damage, they each used a camera obscura to view the sun, witnessing the dark spots move across the solar disk.

Effects

Creates sunspot like phenomenon in the sky that temporarily blocks out neighboring light. The form can last for several days or for a brief few seconds, always changing its shape as it flows and pulse. They follow the user wherever they go, usually lingering on the user’s peripheral horizon or even appearing in darkness, trying to get their attention. Looking directly at it will not result in eye damage and result in only slight mesmerization of the onlooker.
