CTHULIN

Their true name is unpronouncable, however I find disturbing that an early 20th century pulp fiction writer displayed a remarkable prescience about Cthulin culture.

PHYSIOLOGY
An exotic (non-Earth standard air breather) amphibioid. Cthulin can breathe Earth-standard air for short periods of time (1-2 hours), however prolonged exposure will cause severe respiratory damage.

CULTURE
They are extremely evasive about any inquiries about their people.
