OK, sorry I didn’t post this stuff in the first place.
The names I posted here were abbreviations – nicknames that will help us to identify these beings without typing their full 37-letter names every time.

“Khur” is Khurgorbaeyag, “Nomog” is Nomog-Geaya, and “Barg” is Bargrivyek, as you will see in the title of this thread.
Here is an overview of the information on each of these, to tide you over until you get to read the full thing:

Alignment: Neutral evil

Khurgorbaeyag is the patron god of goblins as a race (tolerated to exist by good ole Mags)
