Objective Heuristic Metalanguage
Reference

The Objective Heuristic Metalanguage was a name given by Ana Mireya Fiero to an ancient language of unknown origin. The language is used to worship the Ogdru Hem and is implied to shape the minds of those who learn it into servants of the Ogdru Hem. It is likely that most of the unintelligible phrases spoken by the Ogdru Hem, their worshippers, and the Ogdru Jahad are in this language.
