"It's like they were lost in some kind of fog, drifting in and out.."
DriftingFor a lot of afflicted people, suffering from Eclipsal Memory is much like shifting from dreaming to the real world with the lines blurred to the point of barely being distinguishable. It becomes hard for them to recognize what's real, so while they don't lose their capacity to remember, they eventually are unable to distinguish real from what has become known as the eclipse. There are varying responses from person to person while in the eclipse, some are lucky enough that their eclipse is much like their true life, whereas others are stuck in nightmares until the fog of the eclipse passes. In extremely rare cases, the eclipse never passes, and becomes the permanent life of the person afflicted. When this happens, they fall into a coma, eventually succumbing to their body not being able to regulate itself in response to the real world as opposed to the eclipse.
PassingThere's been many instances of Eclipsal Memory, though it hasn't gained any semblance of proper levels of study beyond some small circles of medical personnel. In more recent years, a tool called the Fogglass has been developed to act as a way to see through the eclipse, however it isn't a permanent solution as the Fogglass deteriorates over time. Research into Eclipsal Memory and the phenomenon of the eclipse continues, and it is slowly gaining traction in the medical profession. It is hoped that a way to reverse the condition will be developed, but so far even magical healing has been unable to do so.
