School of Onomancy (Revised)

True Name is someone's hidden name. They are grant to creatures upon creation by gods to potentially keep those bellow them in check. True Name has its origin in the Words of Creation, the original words that were the precursor to the Celestial Language and even Supernal, the language of Gods. A very few celestials remembered some of these words, whose power was said to be so great that no mortal mind could comprehend more than three or four of these Words of Creation in their true form. True Name isn't just something for show, it is the creatures essence, their core, True Name truly belongs to that person. A normal, non-adventuring human could potentially learn the True Name of one of the Lords of the Nine Hells, and have that Lord under their control, and that Lord could do nothing about it, as devils, demons and other fiends as well as celestials, titans, giants and dragons are more susceptible to their True Names, as they are more powerful beings, and need a way to be kept in check. Learning the True Name of a humanoid, undead, constructs, fey and other creature types not mentioned before aren't affected much by calling out their True Name, but a powerful enough creature or entity, or those studying the arts of True Names can use it to their advantage, even bind, compel and control every creature type. There are sections in the Scribe Orders strictly dedicated to the language of True Names and are kept hidden away from anyone to stop people from abusing them. Some cults spend their whole life trying to find out the True Name of the rival to the fiend they are worshiping. Onomancers seek to use that power. They either use it to find the true names of their allies and power them up with enhancing spells, or they try to find the true name of their enemies and control them. Or they might seek power and find out names of fiends and build an army to overthrow a figure of power or their greatest foe
