first stage of limbus ocs: classic literature and authors (main limbus sinners)
second stage of limbus ocs: slightly more "contemporary"/recent pieces of literature compared to others, maybe some other mediums (roald dahl books, hitchhikers guide, movies and plays start appearing here)
third stage of limbus ocs: relatively modern day works or non-book mediums entirely that are finished or obscure (project hail mary, house, sinners based on stories that have a multitude of different retellings or no concrete synopsis)
fourth stage of limbus ocs: very recent media that is still popular with a living author, maybe a still ongoing story, and could still be considered part of the mainstream of human art that most people in the world are aware of (naruto)
