#1: Did Rod have a “Rod”? In pretty much everything I’ve written regarding Pigtown, no, not really. Rod is a person who, through a series of unfortunate events, became a part of Pigtown–more a part of it’s consciousness than anything else. He can’t leave the premises, or can only do so under special conditions. He’s not quite human at this point, but that doesn’t mean I know what he is.
#2: It’s geographical location is not fixed. Nothing about Pigtown, as a place, is fixed. Pigtown is a bar, or an area surrounding a bar. It could be any kind of bar. Generally it’s located in an urban locale, but this isn’t necessarily always the case. This is less an eldritch thing, and really just a consequence of the fact that Pigtown is a setting, not a world, in writer speak.
