Copperforge

Copperforge is the western Gnome kingdom in the southern portions of Hortiel's Crop. It is ruled by Queen Gerda Sleekrun. Lord Elb Gabber controls the criminal underworld. The gnomes here are industrious and produce a variety of machines. Due to their prowess with machines, the gnomes of cooper forge are the richest kingdom on Sahl. The city of Copperforge occupies the entire southern mountain. There are two gates to the city, the Grand Gate to the east and the Live Gate in the south near the Thornbrush Forest.

Layout
The city itself resides inside the mountain and is composed of eight massive platforms that rotate at different speed. There is a central spire and bulb that house the electrical and plumbing routing. Pneumatic tubes are used for travel between the layers.

The layers are, from top to bottom:

Peak, which houses religious temples (for Sahlen and his children, but not Kloht), meditation chambers, acolytes housing, the Royal Library, and the Peak Gate.

Royal, which houses the royal family, private parks, throne room, and council room.

Political, which houses the great guild halls for tinkerers, automaton makers, bankers, mercenaries, assassins, hunters, miners, enchanters, and public affairs.

Residential, which houses the commoners, merchants, stores, smokehouses, and taverns. The Tequila Mockingbird Tavern is on this level.

Central, which is the largest and is the public space. It houses forums, public baths, and the Bowl, which is an amphitheater used for betting on robot battles.

Forge, which house all of the forges of the city. The sound is deafening. You can find pretty much anything made down here, including: copper pipes, armor, tinkerers, enchanters, and weapon-smiths. The most well known artificer in the city, Klaxxon Carbal, has his shop on this level, the Gearhead.

Prison, which houses the hundreds of prisoners of Copperforge, all of whom are required to wear a copper armband. The Prison level is oddly comfortable. Prisoners work and can communicate to the other levels. Most prisoner are rehabilitated.

Dungeon, which house the irredeemable, sealed away forever. Rumors tell of screams being heard before below the seal, suggesting that some have found a way to survive down there. It is the most recently built disc, only 10 years old. It does not rotate.

The Deep, which is the pit beneath the city. The gnomes do not travel here. The divisions between the planes is weaker the further down you go.

History
Legends state that Hortiel planted a seed that grew into the Copperforge mountain. The gnomes who tried to mine from the seed were killed, but lived like gods for a brief time. The seed is now enclosed in the central bulb and used to power the city and its automatons and weapons. The first gnome, a direct creation of Lothlen, designed and built the city. The Flintborne clan was one of the original gnomish clan and helped design the first disc.

Seventeen years before the descent of the Sahlite over Raufel, one appeared in Copperforge, but it was caught and murdered by the followers of Kloht. The Black Cloaks overran the town, killing all who saw the meteorite, including the tinkerers who went to gather gems. Governor Syle helped them in their time of need.

The route from Copperforge to the port city of Raufel is known as the Coppervein and heavily traveled, though recently caravans have come under attack from a band of orcs led by Kurluk.

With the help from the party from Raufel, Elb Gabber discovers that the Queen is building war machines and weapons in the Dungeon for an unknown purpose. However, before they can be used, the Forgotten, led by Meno, steal them and escape into the city. Ora Stone is able to negotiate a peace, but she is forced to execute Meno on the Queen's orders. The weapons were meant to defend the city and the West from Kurluk and his orcish hordes.

After the battle, the populace is filled with discontent against the Queen's rule and a rebellion stirs, inflamed by Ora, Minnow, and Lynch Pynn. As the orc horde draws closer, Ora and the Queen agree to a truce. Most of the citizens are evacuated to the lower levels and the main gate is welded shut.

As Copperforge prepares its defenses, a terrorist attack on all the discs at once by a doppelganger leaves the city battered. The next day it is beset by the orc horde. Kurluk and several orcs, along with the demon Thaul Alhoon, enter the city. While at the cusp of victory, the remaining orc soldiers are attacked by an eldritch monster. As the gnomes try to bring the mountain down on top of them, Kurluk has Alhoon summon the fiend Orkan to prevent them. However, Andre Monroth convinces Orkan to switch sides and attack Kurluk.

Most of the population, including the Queen, is evacuated out the Peak Gate and head north toward the Steamfang Dwarves. After the party flees the city, Alhoon and Kurluk are able to defeat Orkan and take the mountain. From this new base of operations, Kurluk reforms his army. He strikes another deal with Alhoon and the two form into a huge demonic beast, worshiped by the orcs until Ora Stone blows the seed of the mountain, which destroys all of Copperforge and the orc armies. Kurluk/Alhoon survives, however.
