From time out of mind, the standing stones known as the Circle of Cahervaniel have stood lonely vigil on a grassy hilltop. Sheepherders once moved their flocks over the hill and through the circle, sometimes resting in the cool shadows cast by the ancient stones. Everything changed when a stone finger fell, revealing a fissure in the earth. Now, dark shadows caress the circle after the sun sets. Creatures out of nightmare dance upon the hillside at night. Many swear that a unicorn of deepest ebony now hunts all upon two legs who draw near, while stunted creatures scurry in the shadows, abducting sheep from their sheds and drawing them down below ground for food. After the disappearance of a sheperd, fear grows stronger in neighboring villages. Who will brave the black hollow of the ancient Circle of Cahervaniel? Heroes of stern mettle must descend into the cavity and explore the ancient spaces existing there. Product History "The Shattered Circle" (1999), by Bruce R. Cordell, is a generic adventure for AD&D 2e. It was published in January 1999. Origins: Another Generic. After Wizards of the Coast began publishing D&D, their first year and a half of generic adventures were all classic revivals: returns to RPGA tournaments, to classic adventures, and to Dungeon scenarios. Even "A Paladin in Hell" (1998) was a return in its own way, to the demons and devils that TSR had become afraid of. Wizards was staking out new ground by reclaiming the past. "The Shattered Circle" (1999) was the first generic Wizards adventure that was simply a generic adventure, with no deeper origins and no hidden motives. Artifacts of Note. the foundingstone and the harp Euphonious are both one-off named magic items. However, it's sword Icerazor that's the most interesting. It's said to have grown from a shard of Frostrazor — a sword that would only appear ten months later in Return to White Plume Mountain (1999). There, it's listed as one of Keraptis' four implements of power, alongside Wave, Blackrazor, and Whelm — meaning that Icerazor (and this adventure) are just one step removed from White Plume Mountain itself. Monsters of Note: Chitine. It's somewhat curious, given the Greyhawk and Neverness connections, to note that the chitine debuted in MC11: "Monstrous Compendium Forgotten Realms Appendix" (1991). The spider-humanoids have generally been a Realms creature, featuring in bestiaries and histories for that setting. However, they also received a more generic "Ecology of the Chitine" in Dragon #223 (November 1995), which introduced the choldrith, or chitine priestess. This is their major adventure appearance. When asked about pronouncing their name Cordell says that he "can't be 100% sure of the original designer's pronunciation", but he prefers "KI-TEEN". About the Creators. By 1999, Cordell was one of D&D's most prolific writers. He'd previously authored many slightly related adventures, such as The Gates of Firestorm Peak(1996) and the sahuagin (1997) and illithid (1998) Monstrous Arcana adventure trilogies. This conversion guide allows DMs to run the original module with 5th Edition rules. To use this conversion guide you will need a copy of The Shattered Circle, originally available in hard-copy and now for sale in Digital format at the DMs Guild. This adventure is a generic adventure, not specifically based in any existing setting. Suggestions are given in the conversion guide to place the adventure in the Forgotten Realms.

They say the legendary Ashes of Evensong have been found! In the year 689 DR, the song dragon Evensong was incinerated by Kallurous, a red dragon. In the wake of her death, Evensong’s ashes were gathered into a hundred urns by members of the Harpers. Originally intended as mere relics, the urns fell out of the Harpers’ possession when the caravan transporting them was ambushed. They were thereafter lost to history. Three months ago, stories began to circulate that at least one of the urns has been found. An artificer from the city of Elskar claims to have acquired some of Evensong’s ashes. According to his story the ashes are more potently magical than even residuum, created as they were from the mortal remains of a powerful magical creature burned to ash in the fires of an even more powerful dragon’s breath. This tale is dismissed by most, but certain factions and private interests aren’t willing to reject the possibility without investigation. If true, the artificer may be in possession of a highly dangerous and unfathomably valuable substance. More importantly, he may be in possession of the knowledge of where it came from, and the secret of what happened to the Ashes of Evensong all those centuries ago. In search of the truth behind a rumour that some of the Ashes of Evensong have been found, the player characters find that the Ashes are ultimately incidental to a far more worrying development. The trail of the Ashes leads them to the discovery of a fiend pact warlock operating among the ruling class of the city, a vault of forbidden magics the secrets of which have been breached, and a diabolic artefact about to be reclaimed in the name of a Duchess of Hell. With a focus on investigation, puzzles, and dangerous traps, Ashes of Evensong rewards players for caution and cleverness. Published by Spilled Ale Studios
