Highthorn

Highthorn is an ancient, legendary site located in the rugged frontier of the Sword Coast. Long lost to the annals of history, its true identity was recently rediscovered: the ruins once known as Highthorn are known today as Cragmaw Castle, a ruined stronghold situated to the north of the Cragmaw Hideout goblin lair.

The name “Highthorn” was first recovered by adventurers who found it carved into the stone walls of the Cragmaw Hideout alongside other remnants of a forgotten age. Its exact location was later revealed to seeking adventurers through a divine vision granted by the altar of Ioun, the Knowing Mistress, in Conyberry.

The Golden Age and the Pact of Phandelver

Over a thousand years ago, Highthorn served as the ancient summer seat of the human King of the Pact under a historic treaty known as the Pact of Phandelver. This tripartite alliance, brokered by the fire-hearted King Phandelver II, united three ancient peoples: the human settlers of Highthorn who entered Neverwinter Wood, the dwarves of Axeholm (under Queen Kima), and the elves of the Hand of Sehahine (led by Archmage Larellion). Together with the Gnomes of the Vale, who lent their magical ingenuity, they crafted the legendary Forge of Spells deep beneath the earth.

During this golden age, Highthorn was considered a “mortal dream.” The city was renowned for its beautiful, ivy-wreathed turrets and sunlight dancing on polished stone. Along “the golden road of Highthorn,” human pageantry stitched the seams between stone and song. It was a cultural crossroads where humans dined alongside elven scholars and dwarven lords, serving as the place where the Pact’s ideals lived most vividly. This historic legacy was even written into the cosmos; when the Forge of Spells was sealed, the night sky of the Age of Arcanum was preserved, depicting Highthorn as a shimmering constellation of a great castle with turrets and crenellations alongside the Hand of Sehahine and the dwarven hammer of Axeholm.

This era of cooperation is recorded in rare texts, such as “The Rise and Fall of the Pact of Phandelver” by the Sage of Waterdeep, Elminster Aumar, and remembered by Gotrek, an ancient dwarf who was petrified for a millennium.

The Sundering

As the centuries wore on, the alliance fractured. Mutual suspicions arose, with the elves whispering of dwarven greed and the dwarves scoffing at elven aloofness. Left increasingly isolated as goblin banners and orc hordes stirred in the south, the human kingdom could not hold.

The final fall of the Pact was a rapid, tragic sundering precipitated by the arrival of the Calamity in the north. As armies of orcs, undead, and other monsters led by the Betrayer Gods marched upon the region, the alliance dissolved from within and without. Axeholm was abandoned within days, the beacon of the Hand of Sehahine was permanently extinguished, and Highthorn was brutally sacked—its beautiful towers shattered and its people scattered.

In the final hours before the fall, a desperate warning was left for future seekers. While long rumored to have been left by a deity, the warning was actually recorded by Gond, who was not a god but rather a highly talented dwarven craftsman and the blacksmith of the Forge of Spells during the Age of Arcanum. Expecting to die within hours from the onslaught of the Betrayers’ armies, Gond placed the forge’s defense in the hands of his ultimate creation, the Guardian of the Forge, and prayed that the Archheart might forgive them for their blindness.

Legend says that Agatha, the gentler daughter of Archmage Larellion, vanished shortly before the Hand fell silent, singing of how her friends and grace had forsaken them. Her name lives on as the banshee of Conyberry, and her ghostly form is still occasionally seen wandering near the ruins of Highthorn, waiting for her family to return.

Modern Status and Dark Legacy

Today, the shattered ruins of Highthorn have fallen into dark hands and are known as Cragmaw Castle. Controlled by the Cragmaw goblins, the stronghold was recently ruled by the ruthless bugbear leader, Blarg, who arrogantly styled himself the “King of Cragmaw.” Under the direction of Nezznar (a Drider known as “The Spider”), the goblins captured the dwarf Gundren Rockseeker.

The Spider cared little for the castle itself, viewing it as “broken sticks and stones,” and happily allowed the bugbears to occupy it. However, Blarg took Gundren’s map of Wave Echo Cave, falsely reported that the dwarf was dead, and sent the map to Nezznar. Gundren was actually kept tied up in Cragmaw Castle until Sildar Hallwinter managed to locate and rescue him after the Cragmaw goblins mostly scattered following the Spider’s demise.
