Insiders & Outsiders
Citizens of Nodd are either insiders or outsiders. An insider refers to any organism that originated in the realm of Nodd. They are said to be born of Nodd's unspoken needs, influenced by unknown arcane mechanics.
Insiders can take on any number of appearances, and some are unlike any others. However, there are several that are considered common enough in Nodd that they're identified with names, such as slyne and ravel. Cross-species hybrids are common and referred to simply as hybrids, or some awkward informal hybrid-name (such as a slyvel, in the case of a ravel and slyne mix). Even more common are ambiguous mutt species, which are referred to as “chimerae”.
Outsiders, on the other hand, inexplicably appear before the city's gates, seemingly cast onto its doorstep from another mundane reality. These special creatures are a recent anomaly, and are rather rare, sparking curiosity among insiders. The Council has even taken to calling them the "Chosen Ones" and has established a protocol for ushering new outsiders into the city. Alongside most inhabitants of Nodd, these creatures often appear beautiful, if not divine. Insiders regard them in a wide variety of ways, from intrigue to abject hostility.
Outsiders who end up in Nodd don't seem to remember the series of events directly before they wake up before the gates to the city, but rather snippets of their past life that return to them in dreams and visions.
