Dragonspear Castle

Dragonspear Castle was a dwarven fortress built upon the High Moor during the 13 century DR. It had a long and storied history within Western Heartlands. It served as home to monstrous humanoids, became the battleground for two wars between Faerûnians and devils from the Nine Hells, and was even the stronghold for an angelic Shining Lady and her crusade

Geography
It was built across three low hills on the southwestern edge of the High Moor, east of Trollbark Forest and just north of where the Coast Way joined the Trade Way.

Within the Misty Forest was a small cave that connected to the subterranean waterway that passed under the castle.

Extensive tunnels were dug under the keep, connecting with the subterranean Nepenthe River,  the abandoned city of Kanaglym, and the greater depths of the Underdark.
 * Underground:

The caves and tunnels beneath the castle housed colonies of giant, incandescent fungi, some of which released clouds of deadly mold. The water that passed through the underground river was ice–cold and moved at a lazy place. It was also home to a number of water elementals.

One route of the underground tunnels led to a buried labyrinth. At the very center of this twisting maze, enveloped in an arcane field, rested the powerful artifact weapon, the castle's namesake Dragonspear.

It became infamous for the inter-planar portal located in the dungeon beneath its keep. This portal was linked to Avernus in the Nine Hells and granted baatezu and other fiends an entrance to Toril.
 * Gates:

Structure
The outermost walls of the keep held the Great Gate and nine grand towers encircled the castle's outer ward.
 * Outer Walls:

The six sides of castle's walls were arranged in a shape of a coffin with a head that pointed westward. They stood 30 feet (9.1 meters) above the hill on which they were built, and built 10 feet (3 meters) underground. Four large turrets, 40 feet (12.2 meters) in height, were positioned at the easternmost and middle points of the hexagonal figure. The two barbican turrets, of similar height but smaller width, sat at the two western points flanking the inner gate.
 * Inner Walls:

Within the courtyard, in front of the main keep was a ruined shrine dedicated to Tempus, the Hold of Battle Lions. Although the building itself was destroyed, its altar held a holy relic that allowed the castle's portal-sealing wards to be replenished.
 * Courtyard:

Also outside the keep were several large iron cages that dated back to the hobgoblins that held the keep prior to the First Dragonspear War. Since they have been used by the soldiers of the Shining Crusade, and the group of vampires that dwelled within over a century later.

Perhaps the most notable feature feature of the castle's keep was the skeleton of a colossal red dragon that draped over battered rooftop. The structure itself was in great disrepair, with glaring holes and cracked stones.
 * Main Keep:

Interior
The ceiling of the keep was 30 feet (9.1 meters) above its stone tiled floor, at the highest point of its vaulted ceiling.
 * Ground Floor:

Standing in the keep's anteroom were four marble statues depicting human champions wielding swords and shields inlaid with the images of dragons.

The walls of the main hall were adorned with several tapestries, decorative shields, and six gargoyles. Its floor comprised stone tiles that were laid in a diagonal orientation. At the back of the hall was a smaller chamber containing stairs that led to the castle's basement.

The northern wing served as the castle's original barracks. Despite its disrepair it offered decent shelter, and was even used as a makeshift boarding house for Coalition forces decades after its original occupants.

While it was later destroyed, the southern wing once served as the castle's library and held a private study.

Like the keep above, the basement of Dragonspear Castle comprised a long, central area connecting several smaller chambers along its north and south–facing walls. In the center of the basement's stone floor was a large, circular mosaic depicting Daeros Dragonspear, mounted atop Halatathlaer wielding his iconic lance. Hidden beneath the mosaic was a secret compartment that held Daeros's personal suit of armor.
 * Basement:

Along the northern wall of the basement were a few smaller chambers, containing an underground well, a small shrine and one that held massive sealed doors. Behind these doors was a small cave that held the portal to Avernus, whose repeated opening plagued the people of the Sword Coast.

The southern rooms of the basement contained a small storage area, the castle's larger and its kitchen. In the chamber beneath the keep's southern barbican turret was a shaft that led down to the underground warrens. This "passageway" was originally used for waste disposal by the castle's original inhabitants.

The Warrens was a name given to the cavern directly below Dragonspear's cellar. Attached to the cavern was a narrower passageway that opened up the underground Nepenthe River. The warrens were used by the Shining Crusade a staging area for moving supplies and troops in and out of the castle.
 * Warrens:

Somewhere beneath the castle was vast labyrinthine maze. For some time it was various subterranean monstrosities and malicious fiends, including a greater guardian daemon. Hidden within its center was the artifact known as the Dragonspear, which was recovered and destroyed during the Second Dragonspear War.

History

 * Daeros Dragonspear emerged from Kanaglym, bearing a fortune in gems. He built Dragonspear Castle around the lair of his copper dragon companion Halatathlaer, above the dwarven kingdom.  The castle became a safe haven for dwarves within the region and their martial prowess helped ensure its security.

 * Ithtaerus Casalia created the first portal to Avernus in Dragonspear Castle. He bound the dragon Halatathlaer and tricked Daeros Dragonspear into entering the portal, an act that claimed his life. Afterwards, Ithtaerus lured other dragons to the castle with vision of a free dragon hoard. Three hopeful dragons arrived and battled each other, slaying Halatathlaer and demolishing most of the fortress. The surviving dragon, Sharndrel, was incensed by the deception and slayed Ithtaerus. Halattathlaer's spirit remained connected to the castle, and later its ruins, for nearly a century.

 * The First Dragonspear War began as a mist cloaked the ruins of Dragonspear Castle, said to have been resistant to even the dispelling efforts of Khelben "Backstaff" Arunsun. The forces of Waterdeep and Baldur's Gate once more converged on Dragonspear Castle, setting fire to its structures and defeating the devils within.

 * The Second Dragonspear War began as devils led by Baazka retook Dragonspear Castle and built an army of humanoids and a dominated black dragon. This fiend-led army destroyed The Way Inn and attacked Daggerford before being defeated by a motley force of combatants led by a handful of adventurers. The castle was cleansed of any demonic forces and the wards and shrine protecting its underground portal were reinforced.

 * The aasimar Caelar Argent gathered an army of zealous warriors and mercenaries, calling it the Shining Crusade. They occupied Dragonspear Castle and led a campaign against the Bhaalspawn that saved Baldur's Gate from the machinations of Sarevok. Once again the armies of Baldur's Gate and Waterdeep came together, and along with the armed forces of Daggerford, formed a Coalition that fought against the crusade at the siege of Bridgefort and again at the castle itself.

 * Following the battle at Dragonspear, the portal to Avernus was briefly opened by an imp masqueraded as the human cleric Hephernaan. No fiendish forces escaped from the Nine Hells however, due to the efforts of the Bhaalspawn and their fellow adventurers.


 * Before the :
 * The castle came under control of undead horrors that were led by the entity known as Born.


 * Circa the :
 * The rakshasa Nadir convinced the Szarlnaxi vampires to open the weakened seal that shut away the portal beneath Dragonspear, so that they could free the soul of their former leader, Voltan Szarlnaxi. In truth, Nadir sought revenge on his arch-nemesis, the paladin of Lathander Sir Isteval. The portal to Avernus was briefly opened once again, but closed in short order thanks to the efforts of Sir Isteval and the adventurers that accompanied him.
