In the latest response (link to the last comic), Altumar shared information that he managed to duplicate some pages of Cretapars and "immortalize" them on sea leaves in his Underwater Library. I think these pages could be a great addition to our collection, as they are duplicates, but in a slightly different form:
Some pages we've seen only in fragments, though they are no less interesting. Analyzing the images on the pages reveals a soft engraving or 'embossing' of lines on soft leaves, followed by rubbing in some pigment or similar substance. This is likely essential for the viverans, so in case of errors, they can correct them and simply not cover them with light spots later...
