The Glutt Inn

Stretching 30 feet overhead, a sign of red, yellow, and royal purple flashes with stilted movements of a dragonborn shoving a fork of meat into his gaping mouth. Just as tall as the sign, the building behind is wreathed in dozens of colorful lanterns and soot-covered awnings, that support a massive banner that reads: "The Glutt Inn"

The Glutt Inn (26x26)
The first floor is a wide open space is crowded with tables made of metal. Hanging from the stone walls are hundreds of worthless items from around the multiverse: gears from the great machines of Mechanus, flasks of eternal fire from the City of Brass, a broken wagon wheel from the demiplane of dread, and numerous other novelties.
The servers and kitchen crew of the Glutt Inn were all either hand-picked by Dral during his travels through the multiverse or consigned to him by his archdevil forebearer when the tavern opened. Regardless, the staff are more than capable of running the establishment in Dral's absence, even if they only bring a fraction of his enthusiasm and eccentricities to daily operations.
Dralithoric: The owner-operator of the Glutt Inn is a large dragonborn named Dralithoric. His curious demeanor, red swooping horns, and bombastic voice immediately set him apart from his fellows. His true love is experiencing decadent, grotesquely ostentatious food and decor fitting for both mortals and devils alike. As such he has joined the Society of Sensations, though he primarily focuses on obscure and interesting foods the leadership was scared to deny him membership.
He is something of a plane traveler, using his infernal connections to visit the planes of Gehenna, the Feywild, and even the relative paradise of Bytopia. While in such far-flung locations, he constantly eats the native cuisine and learns what he can about their traditions before returning to Ribcage. He usually brings trinkets from everywhere he travels to adorn the walls, and the (relatively) lively atmosphere is a welcome respite from the otherwise .
Dral is the descendant of the archdevil Titivilus, the adviser to Dispater, and a red dragon spawn of Tiamat named Yzihentylth. He has taken well to the role Titivilus put to him well, offering information and relative safety to mortals, especially adventurers. The information given, of course, comes directly from Titivilus' many agents in order to further machinations so far beyond mortal understanding as to be unknowable. If the mortals under his roof seem like capable agents of change, Dral reports their names, equipment, and relative abilities to Titivilus, who has endless uses for powerful mortals.

The Sisters

Rather than rely on the Blackguard who are purely self-serving, Dral relies upon Sister Shara to provides protection to the inn. He found her upon the material plane during one of his ventures, and offered her a place where the sun could no longer threaten her. She feels compelled to uphold the pact, and has not yet wished to venture far from her new home.
Sister Shara: Shara is a female moon elf turned vampire. Her once bright flickering hair has been dulled by undeath into a dull orange that smolders around her shoulders. Her one job, which she revels in, is to keep guests and fiends who frequent the tavern in line
The Nine Hells has been a haven to the ageless vampire, as neither sunlight nor running water exists in Ribcage, offering her a freedom to roam that she'd never experience in the Prime Material world. She asks each mortal that crosses her to willingly give their blood to her. If they refuse, she flips a coin and lets fate decide if she pursues them further. She gives particular attention to powerful female warriors and spellcasters, but she has very little need to feed at this extremely late stage in her life.
To ensure her eyes and ears are everywhere, Shara returned to the home that betrayed her and slaughtered them all, but not before enthralling three powerful female moon elf wizards to bolster her ranks. She has considered turning the others, but is uncertain if this would attract too much attention in Ribcage.
Sister Demoria - She reeks of nobility. She wears extravagant silk dresses, golden eye and lip makeup, and carries a gilded basket hilted sword at her hip. Having spent two centuries practicing the art of bladesinging, she is now seldomly seen more than a stride away from Sister Shara, who she believes is a trusted friend an ally.
Sister Binala - She stands nearly a foot taller than Demoria or Elsys. Her willowy form is draped with sashes, robes, and small trinkets, such as vials of liquid, thin chains, palm-sized notebooks, and dangling gemstones. Most of her life has been spent learning and perfecting transmutation magic. She sometimes uses her magic for the betterment of the tavern, but keeps many of her tricks to herself.
Sister Elsys - She covers the hollows of her eyes and a stripe of flesh from the base of her nose down her lips all the way to her navel in soot-black war paint. Her black hair is often pulled into a ponytail.

Patrons

Barius Sharpsplinter - One common sight in the inn is the smoothest of the lot is Barius, a quick-tongued and satirical poet who somehow has managed to not lose his head yet to the Blackguard. He has made a fortune from intrigued visitors who enjoy the stories, information and wit of the Bard.
Surefoot - A competant ranger who has love of the fiends next door, he'll take any job with good pay and a reasonable chance of hurting them. The bariaur is one of the few people who can guide one through Baator with success, for a price. He has poor 'people skills', losing more than one interested party to his bad manners.
