The Dragon Macrocosm is the setting that all of my characters and stories takes place in being an infinite collection of multiverses and the timelines found within where all or nearly all of the living creatures are Dragons. The definition of Dragon in the Dragon Macrocosm is any living being which is a part of the Sauropsida taxonomic clade. That red line is the Bridge Between Worlds a massive indestructible bridge constantly shifting like an infinite spider web that connects each and every multiverse and timeline together!
