Honestly, if I were to give Cryptics a 'descriptionspren' name, I'd call them truthspren. They seem very interested in how something can be true and not true at the same time - like metaphors - and the Lightweavers seem to be all about seeing the truth in yourself and the world around you (and then hiding it again...)
Of course, I'm generalizing from one example here, but everyone does that. At least, I do.
