The bestiary of Goodbye Strangers holds some interesting creatures. Some are harmless, some are not. But the bestiary holds some disturbing creatures under its sway.
- Being in close proximity to the Boguldromi slows the perceived flow of time. Those who stray too close will find themselves in a state where they experience a single minute as several hundred years.
- The page image depicts the lume, a stranger that is always accompanied by what appears to be a disembodied head. It seeks out people who are in physical peril (e.g. a car crash) to suffocate them by pushing it's hand down the person's throat. Occasionally, the lume generates another severed head that looks exactly like the killed person's.
