Won from a clutch of dragons, Dragonsden was intended to extend the dweorhin’s reach even further into the depths of the earth, but the maddening nature of the shimmering ebony caverns proved stronger and more intractible than the wyrms it had housed. The dwarves fell to fighting among themselves in bitter conflicts that grew more and more depraved, until one clan sought an alliance with the duergar of Temâthdrêllur. The coordinated dark dwarves swiftly conquered the fractured smallhall, and have held it against repeated assaults from Diamondsdelve. The original dweorhin clans survive, though many among them secretly believe they are no longer worthy of life. The fact that they have become duergar themselves is meaningless beside the knowledge what they did in madness.
Hammerscale – Smallest of the Dragonsden clans, the dwarves of Hammerscale resisted corruption in vain. Their skill in manufacturing weapons and armor from the bones and scales of powerful creatures is steadily turning to necromantic avenues, avenues first ventured upon with the bones and teeth of their fellow dwarves.
Izakorn – A minor clan in Darkhome, saddled with tasks of administration and accounting, the trueborn duergar of Izakorn clan grabbed at the opportunity to move to Dragonsden. They rule Dragonsden in the name of Temâthdrêllur, taking every opportunity offered to flaunt their power over the native clans and the Darkhome duergar soldiers stationed here. Few will admit that the transformed dwarves of Bàdrül frighten them, and fewer still will confess to the twisted thoughts that come more and more frequently in their own minds, tortured thoughts of blood and madness.
Murkhelm – Miners and delvers, the Murkhelm dwarves fell furthest into depravity, slaughtering members of the other clans and feasting on the corpses. Now Murkhelms have withdrawn into their own clan, avoiding all contact. The few Murkhelms that still venture among the other dwarves don’t speak, and wear sealed great helms of black iron. A sinister aura surrounds them, and even the trueborn duergar of Darkhome give Murkhelms a wide berth.
Woestone – Loyal guardians and protectors, the Woestone did their duty too well – in their madness, they sealed their children and elders in impenetrable vaults of stone for protection. When the duergar arrived, only withered corpses and gnawed bones remained in the vaults – while the Woestone fighters had gone to war to protect their children, the children had starved to death. The Woestone clans guard the vaults as sacred places, and leave living sacrifices for the hungry ghosts.
The Ebony Vault – The last dragon of Bàdrül fell here in darkness, and the vast cavern is the heart of the Dragonsden smallhall. The vault is imbued with malefic inhuman power, and is a node for the Path of Madness. Draconic casters may access a different path, but the nature of that path is unknown.
The Woestone Tombs – Imbued with power by the deaths of the Woestone innocents, a few Woestone casters have turned the tortured stone to their advantage. The Woestone Tombs are a node of the Revenant's Path, a fell tradition of necromancy and death.
