how come some adult trolls have names and others have titles, and those with titles can get them changed? The adult trolls with names dont even have names that follow the rule of 6

A lot of the ancestor stuff was first talked about in Mindfang’s journal who as we know has a liking for the number 8. Presumably Hussie gave 8 letter titles because we were reading about it in said Journal and then the naming convention just stuck. But they all have names as well as their titles.
