That sound interesting actually. As if Light World could in fact be within the literal Omniverse Nexus.

As far as I know how it's planned, Amie is the only character that actually lost her memory because of the way she entered it. Her currently unspecified disease gave her retrograde amnesia, so her memories manifest themselves physically in the form of objects that can help her focus and recall facts.

Bella, Savien and Magne do have clear recollections of their time on Earth. As for Charlie, she does have brain damage - haven't decided on how this affects her memory, but she is actually not too concerned about her previous time on Earth, adapting to Light World to the point where she herself could pass as a native inhabitant. How she got this brain damage though hasn't been specified. For all I know, she could be from another version of Earth and be utterly confused and dissociated from reality.
