Hammerhal, also known as the Twin-Tailed City, is the greatest and the spirit capital of the Cities of Sigmar, cities built after the end of the Realmgate Wars around the Realmgates claimed by the Stormcast Eternals. It's known as the Twin-tailed City because it's two settlements, Hammerhal Aqsha and Hammerhal Ghyra, ruled as one, one on each side of the Stormrift Realmgate.
Before being reclaimed, thirty chambers struck at both sides of the Stormrift Realmgate battling the orruk tribes who worshipped it as the Maw of Mork. Their tribal kingdoms had long fought over the mystic portal, raising sprawling fortifications upon its twinned thresholds and invading one another through its crackling depths. Given common purpose by the Stormcast attack, the Morkmaw tribes unified. Only after long years of fighting - and with the aid of the Hallowed Knights, the Anvils of the Heldenhammer and several other Stormhosts - did Sigmar's warrior at last defeat the orruk scourge. To the Hammers of Sigmar went the honours of raising the first Stormkeeps around the Realmgate.[4a] The city that followed was named after them.
Reaching up from the bedrock on both sides of the Stormrift, Sigmar's warriors discovered rich outcroppings of realmstone. Formed from the concentrated magics of the Mortal Realms, these volatile crystals were a valuable yet dangerous source of arcane power first harnessed by the renowned architect Valius Maliti. The energies that poured from their central lodeshards were crucial in speeding along the construction of Hammerhal, fuelling the efforts of the Ironweld engineers to raise new defences and expand the city's boundaries. It was the engineers who - with the aid of the Lord Relictors - caged the energies of the realmstone, building elaborate sigmarite machinery around them to harness their volatile sorcerous emanations. In Hammerhal Aqsha, those wrathful energies powers a vast shield of flickering lightning, while Hammerhal Ghyra funnels them into protective wards to confuse and misdirect hostile invaders.[4c]
In the Time of Tribulations the two hundred and forty-four Lords of the Heavenhall debated fiercely about what action to take before Morathi the High Oracle of Khaine arrived. She quickly addressed them all and stated that This council must put aside its differences immediately and send every available army to Shyish, or the forces of death will overwhelm us. Despite some initial opposition she convinces them to send the cities armies to join her own in attacking the Realm of Shyish 
In the aftermath of the Necroquake the dead arose across the Realms and in Hammerhal Ghyra they clawed their way out of the tombs in the Azyrite necropoli or the blessed soil of the Shadeglens and the defenders of the city were hard pressed to destroy them.[10a] Meanwhile in Hammerhal Aqsha, forgotten armies of deathrattle warriors suddenly stirred themselves and tore free from the boiling mud-flats and marched on the walls.[10b]
Hammerhal Aqsha is located in the Ashlands in Aqshy. It's a harsh and heavy fortified place with towering bastions and batteries. It's many pendants and banners dance on hot, angry winds. It is protected by lighting shields while mobile forts seek to expand the city boundaries.
The cities defences are maintained by the genius of the Ironweld Arsenal, which have a strong presence in the city. The surrounding land is purified by the self-flagellating processions of Devoted of Sigmar.
In exchange for a steady supply of foodstuff from Ghyra, Aqsha provides a constant stream of molten rocks.
Locations in Aqsha
- Adramar Rift: At the northern edge of Cinderfall District lies the unfortunate by-product of the tectonic trauma caused by the foundation and excavation of Hammerhal Aqsha. The city's rifts have either been filled with duardin mines and engineworks, or left as impressive reminders of the scale of civil engineering within the grand city. The Adramar Rift cuts through several major districts and is the main thoroughfare by which merchant trader airships travel through the city.
- Alchemists Guild.[5a]
- Ash Hand Burrows.
- Ashbark Tower.
- Black Dust Alleys.
- Black Fields.
- Blackglass Guilds.
- Blackwood Town.
- Bloom Gate Terrace.
- Bones of Kazarig.
- Brass Mire.
- Briar Bridge.
- Briargate Wood.
- Candle Town.
- Charcoal Hill.
- Cinderfall District: Cinderfall was once a prosperous and highly trafficked trading zone, but the ever-expanding nature of Hammerhal Aqsha meant that eventually the affluent merchant houses and foreign traders moved on to pastures new. In their place rose the Spice Guilds and criminal gangs, tempting a different class of trader to the great rift-docks that border the northern edge of the district. A remnant of he former Grand Bazaar remains in the form of the bustling Riftmarket, but the air of legitimacy is now a front for the trade of illicit goods and a thousand different flavours of vice.[4d]
- House Venargo's mansion: Just outside the Riftmarket stands a large mansion built in the Azyrite style that seems strangely out of place amid its ramshackle surroundings. A black iron fence surrounds the complex and guards are stationed at the front gate at all times, wearing fur-collared longcoats over silver breastplates engraved with the sigil of House Venargo (an open palm bearing a radiant diamond) and ceremonial masks they never remove. The family Venargo controls the trade and maybe nearly the entirety of the vice within Cinderfall and its surrounding districts.[4e][5a]
- Baugren's Bountiful Bazaar: A slightly grimy but impressively large converted warehouse operating under the thinnest facade of respectability, the bazaar is filled with many varied and esoteric items and staffed by a human called Baugren.[5a]
- Chapel of the Shattered Blade: This is a shabby, run-down church of worship to Sigmar. It venerates Saint Rubeus, a legendary Warrior Priest who led the first consecration of the city and fell in battle against the orruk hordes of the Bloodscalps. The chapel is usually attended to by Brother Bargo Culven.[5a]
- The Guild of Certified Thaumaturgists: A ramshackle array of spiral towers and smoke-belching laboratories with a sign that claims this Hammerhal Aqsha's centre of alchemical and metallurgical knowledge. The guild was set up by a group of students thrown out of the city's famed Alchemists Guild for dangerous or unethical experiments, usually both. [5a]
- Red Yugol's Revelrie: At the southern edge of the market district lies this garishly painted field of tents bedecked with banners, flags and leering masks. Faces painted like beasts of the wild, dressed in colourful rags and brandishing rattles, drums and tambourines, Red Yugol's entertainers prance and caper about, beckoning, cajoling and threatening tourists, drunken sailors and travelling merchants into entering the Revelrie. At the very centre of the grand marquee dwells the enigmatic soothsayer and compere Red Yugol himself.[5b]
- The Riftmarket: Running parallel to the Adramar Rift at the northern edge of the city is the mass of tents, warehouses, shopfronts and forums that makes up the Riftmarket. Merchants and traders from across the Mortal Realms flock here to sell all manner of ephemera, from exotic creatures to precious magical items. The largest and most extravagant stall belongs to an aelf named Asterion.[5c]
- Toil's End: Underneath this bar, Olrig runs a free-for-all underground fighting tournament where a number of notable local brawlers compete in bloody, bare-knuckle bouts.[5c]

Hammerhal Ghyra is located in the Jade Kingdom of Verdia in Ghyran is a city of golden domes and celestial spires. This city channels the lava that flows from Aqsha into carefully cut trenches that forms a wall of fire that hold back the plants of Ghyran. The air is noted by many visitors as tasting of cinders and smoke and the atmosphere as wet and humid. [3b] It is known as a stronghold of aelf-kind and many Free Peoples with parts of the city given over to vast groves of trees.[3c]
Locations in Ghyra
- Aether Dock: A ring of stacked warehouses with a canopy of high altitude quays and berths.[3a] Due to the nature of the realm, these are all plagued by growths of vines, mould and weeds.[3b] Thousands of airships, leaf-boats and sky-cutters arrive and depart the city every day. [3e]
- Fire-Bastions: Constructed by the Ironweld Arsenal and constantly fed by lava from the realm of fire via immense stone runnels to keep the flora of Ghyran from overwhelming the city. As the flow is redirected, so new tunnels are created and old empty ones are built over, although some express concerns about what can inhabit them.[3d]
- Shadeglens: Ancient burial gardens whose caretakers are pledged to Alarielle.
There is a constant flow of molten rock from Aqsha and in return Ghyra provides the Aqshyan districts with food. Ghyra imports both stone and timber for building as the inhabitants are forbidden from logging in the realm as per the ancient laws of Alarielle, this is strictly enforced by the local Sylvaneth.[3e] Ghyra uses its carefully channelled flow of molten rock to direct broad defensive canals in order to hold back the overwhelming fecundity of the Realm of Life.[4c]
By day, thousands of airships, skycutters and lava-cogs make their way to dock at the city's trading districts, and the rift-docks echo to the sounds of sailors and labourers shifting a bewildering array of exotic cargo and livestock from their vessels to the merchants' stalls and the dockside warehouses. Riftsiders tend to be hardy, practical folk, well-muscled and sun-beaten from many years of physical toil undertaken in the blazing heat.[4b]
The city is defended by several armies, including twelve chambers of Stormcast. The Hallowed Knights are part of this powerful force and have sworn an oath that Hammerhal Ghyra will not fall while the faithful stand.
