"For untold eons, Eshebala ruled over Vulgarea, the 193rd Layer of the Abyss...content to revel in hedonism, corrupt the hearts of her dwindling followers and inflict petty cruelty. Yet, if there are days in the Abyss, there came one when she realized she despised her own province. She hated demonkind. She hated the Abyss. It had become unbearably tedious, spent...done. The burgeoning goddess decided she would dip her toe back into the lives of mortals, and quest to remember...to understand her own existence...But that was a lofty goal for a mind that had long ago begun to unravel. Instead...She is learning that all she has left is cruelty...and it was always cruelty that gave her power, so she now believes, to the woe of any who cross her path." Partly inspired by a scant notation by Carl Sargeant in 1992's TSR book Monster Mythology: "Eshebala is the foxwoman deity of vanity, charm, greed, and cunning. Her symbol is a female fox. Eshebala appears as a foxwoman, a shapely fur-covered female with a fox’s head, or as a beautiful young elf maiden. She is bedecked in rich clothing and jewels, and carries a silver mirror. Eshebala’s realm of Vulgarea can be found on the 193rd layer of the Abyss. She is wily and vain. She favors beautiful things and collects jewelry and art, the tackier and flashier the better. She prefers to overcome her opponents using subtlety rather than force, seducing and devouring out of boredom. She loves gossip, and always insists on being the center of attention. Eshebala is a patron of evil shapeshifters who use their wits and wiles before resorting to violence." Eshebala is a true chaotic evil demon goddess, behaving 100% true to form, and an extremely challenging opponent to take down for your players.

One crazy night in Waterdeep. Start as tavern bouncers. End up on the Astral Plane. All in one crazy night in Waterdeep. The party has been hired for a simple mission: make sure the Slumbering Prince tavern doesn't get wrecked during the rowdy Midsummer Festival. And what better motivation than 200gp per person for a single night of work. Sound too good to be true? Well, here's the catch: all damages to the tavern are to be deducted from that amount. And there is no shortage of festival-goers looking to unwind by wrecking other people's stuff. Over the course of the festival, the party must deal with drunken wizards, vain bards, loud goliaths, incompetent parade goers, complaining neighbours, disruptive satyrs, aspiring cultists, and a full-on tavern brawl. As well as an unusual number of strange slugs crawling around. Slowly they become aware there is something off about the Slumbering Prince. And when a reckless noble disturbs the secrets beneath the tavern, our heroes must soon delve into the hidden dungeon themselves. Down below, they discover the terrible threat: a planar rift that can only be opened on Midsummer's Eve, and the slumbering demigod that awaits beyond, the great astral slug Cthumbra!

"The longest, and perhaps strongest, AD&D adventure we've ever done." The fabled Mace of St. Cuthbert has been lost from the sight of both human and demi-human for many centuries. Some claim it lies at the heart of an active volcano, guarded by salamanders and flowing lava; others swear it lies buried deep inside the earth, warded by powerful magics raised by those who would see its power denied to the forces of Law and Good. A few assert that it has never left the possession of the Saint, and even now he holds it in his strong right hand. But a few claim that none of these are so that long before the Sainted Cuthbert rose to his exalted station, his mace was hidden away from those who would steal it before he returned for it, hidden away outside the bounds of normal time and space, in a place so outlandish that the Mace's power and destiny would be unknown and unknowable, and thus safe.
