Narratypes are a unit of identity our system experiences in relation to our innerworld narrative. A narratype is a character, animal, song, and/or concept you are connected to and that, in the context of the innerworld narrative, you are, but you do not consider yourself to be this thing outside of the narrative.

The innerworld narrative is something that exists in our system as an allegory for trauma or life events. Basically, we introjected a lot of stories from media and folklore (including Christianity), such that there were parts of our system where certain stories like The Lion King or The Book of Revelations were going on in the headspace, or where figures from those stories believed they would act out those stories someday but potentially with certain twists.

For example, Hellfire City (in East Voidelia) is based on Biblical concepts of Hell, as well as the Book of Revelations. They believed that they were in Hell and the West Voidelian part of the system was Heaven. One headmate even believed zhe was the Whore of Babylon.

As a result, some headmates may believe themselves to be roles from the Bible, such as the Antichrist, that could be considered mythical figures, but that are also part of delusions for some people. In our headmates' cases, though, it is neither, but rather a reflection of the innerworld.

For example, there is an important part of the narrative of East Voidelia in which one headmate, Morlock, is rightfully considered the Antichrist. He recognizes this is important in the innerworld narrative, but he does not have delusions that he is the Antichrist in the outerworld, and he also does not consider himself kin with the Antichrist in a mythological way. He is only the Antichrist in terms of the innerworld narrative.

Therefore, if Morlock's identity as the Antichrist is given as a narratype, especially since it isn't listed in other sections, this eliminates any confusion about on what level Morlock's identification as such takes place.

To give another example: Blue would often pretend to be characters like Simba (The Lion King) or Fievel Mousekewitz (An American Tail), and by doing so, he would be able to interact with headmates like Nala or Tanya, who were the sisters of those characters.

In the innerworld narrative, however, Blixa had to become Blue and take on the identities that Blue used to have. Furthermore, Blixa's Unification of the system is part of an innerworld prophecy regarding the return of figures like Aslan (The Chronicles of Narnia).

Therefore, if Vyvian or Elliott consider themselves to have certain fictional narratypes, they might not genuinely be kin with those characters, but it was important that other headmates who are fictives DO see them as those characters in some way.

While the particulars of what it means for something to be a narratype are given on the individual page linked via that narratype, those are some examples of what it means for someone to be something in the narrative but not in an otherkin or alterhuman way.
