How I personally clarify these guys, featuring some doodles
Examples: humans, monsters, amalgamates, a monster with a human soul
A usually manmade object, set of objects, or a digital concept with no soul that has been brought to life by a dark fountain and does not have life outside of it, formed based on a lightner's will
Examples: a playing card, a doll, a piece of electronics, a weather broadcast, a pile of props/decorations, a shadow casted by an object, a spam email, an antivirus
A darkner formed in the image of a lighter that includes their dust(presumably a corpse in the case of a human) can only exist in specific darkworlds created by someone who knew them in life
A living being without a soul, that gains sentience upon being in a darkworld, similar to a darkner, presumably not only Plantae but also Fungi, and other such non-Animalia
Examples: flowers, cactus, cannabis
An entity given life via a dark fountain that is not based on an object, an entity that's entire physical existence is based on darkness at an artificially lowered level
Examples: titan, titan spawn
An entity without a soul given life via determination, which contains the dust of a monster, however instead of a lightner's will being turned into a fountain, it is extracted and condensed into a physical vessel, that exists in the lightworld in a physical lightworld body
(I didn't make art for this one because we currently don't have any characters following this description)
An entity without a soul given life via determination, however instead of a lightner's will being turned into a fountain, it is extracted and condensed into a physical vessel, that exists in the lightworld in a physical lightworld body
Examples: no current canon examples, however the closest example I know is undertale au Tenna and spamton, but if they didn't have lightner-like bodies
