That leads me to another question. What are the baernaloths? Are they the equivilant of demon lords for the yugoloths? Or is the Oinoloth the yugoloth version of a demon lord?
They don't really have an analog among the other fiends. They're the first fiends, they created the 'loths as servitors, and they also created the obyriths and ancient baatorians. They then largely abandoned the multiverse/left/went mad, and the few remaining are either vastly diminished in power or members of a group called The Demented that still manipulate the 'loths from behind the scenes. They're not like demon lords or diabolic nobility, because they don't hold any position of proper authority within the yugoloth hierarchy. They exist outside of the 'loth power structure. They're essentially the equivalent of spiritual authorities compared to secular powers like the Oinoloth, General of Gehenna, etc. Most 'loths aren't even aware that they exist.
They operate by providing advice and direction to the most powerful 'loths (whether they want it or not), and I take it a bit further in the storyhour by suggesting that they exist in a somewhat parasitical/symbiotic relationship with the most powerful yugoloths, one baernaloth inhabiting each of those unique 'loths, acting like a very real inner voice to guide and push them towards their own goals.
Originally I planned to do something similar in the 4e Marauder article, with her having been so inhabited by one of the baern. She demanded authority and power after having served as a behind the scenes puppetmaster for her infecting baernaloth (The Blind Clockmaker) for thousands of years, and it had the Oinoloth place her within Sigil. Of course that was largely a sick joke on the baern's part, because while finally giving her an opportunity to act in her own selfish interests, Sigil was the one place where she could never truly rule, because of the Lady of Pain providing a very deadly, bladed, glass ceiling if you will. But at the same time, Sigil was the -only- place in the multiverse where the Marauder could ever truly be alone and private, with the baernaloth being unable to intrude, speak, or possess/control.
Aaaaand that never made it to print. It got killed in a very late rewrite, five months or so after the draft was originally accepted. I tried, but little that you can do except what an editor requests.
