Kalidar - Notable locations: Hive Kimeradon / Scumtown - Initially intended as Kalidar's sixth hive city, the construction of Hive Kimeradon was abandoned before its completion, the members of the construction team driven insane by over-exposure to the rich veins of Lorelei in the Ozymandian Basin. The unfinished transit tunnels and first subterranean levels were progressively claimed by the free desert tribes. The sandscum improved and extended on the initial works to turn Hive Kimeradon into their own modest city, colloquially known as "Scumtown."Hive Meradon / Orktown - Before the Kalidar War, Hive Meradon was the most productive of Kalidar's hive cities, its nominal industrial output being estimated at 36 megatons of refined Lorelei per Terran year. As Kalidar's most important city, Hive Meradon was also the seat of the planet's local government. At the beginning of the Ork invasion, Hive Meradon quickly fell to Gratzdakka's troops, who established their base of operations in the remains of the Governor's Palace. Having proclaimed himself "King of Hive Meradon", Gratzdakka ruled over an enslaved local population to which were added captured soldiers or local humans and mutants. This oppressed workforce was put to use both in the Lorelei mines and the construction sites where several Stompas and one towering Gargant rose over the desert sands. Before the arrival of Imperial reinforcements, the local population had begun calling the fallen hive "Orktown," a name that was kept in use until Hive Meradon's liberation in 397.M41.Hive Modulus - One of Kalidar's five official hive cities, Hive Modulus gained an increased importance during the dark days of the Kalidar War. Located on the frontlines of the war against the Greenskins, Hive Modulus became the staging ground for the regiments of the Astra Militarum tasked with the reclamation of Kalidar.Kostoval Flats - Geologically speaking, the Kostoval Flats were once the bottom of an ancient sea, the desert giving away to great salt-plains which have given the Kostoval Flats their name. At the centre of it stands the Urta Mine Complex, one of the most profitable Lorelei mines of Kalidar's equatorial region. By the time Imperial reinforcements arrived on Kalidar, the Orks had pressed nearly to the gates of Hive Modulus and were besieging the Urta Mine Complex. As commander in chief of Battlegroup Kalidar, Captain-General Iskhandrian of Atraxia marked the Urta Mine Complex as their first target and the Imperium committed the majority of their mechanised troops in a surprise attack against the Orks. Unfortunately, the attack ran into a well-prepared ambush which cost the Imperial troops dearly. The losses in what Imperial historians later called "the Kostoval Rout" included the venerable Shadowsword Lux Imperator, a vehicle Gratzdakka himself claimed and converted into his personal Battlefortress.Macaree's Tablelands  - The Macaree's Tablelands are another part of the desert to the West of Hive Modulus. After their initial defeat, the Imperial forces broke through in the Macaree Tablelands, even lifting the siege of the Urta Mine Complex in the process. While the army was resting and celebrating their newest victory, Gratzdakka sent out Ork Kommandoz who successfully infiltrated the Imperial camp and penetrated General Iskhandrian's Command Leviathan, the Magnificence. Although the general himself was never truly at risk, several officers were killed, tanks were booby-trapped or disabled and one Enginseer was abducted, providing Gratzdakka with the knowledge required to reactivate the captured Lux Imperator and its powerful Volcano Cannon.Ozymandian Basin - The Ozymandian Basin harbours Kalidar's greatest and purest deposits of Lorelei crystals. The Basin owns it name to the ring of concentric mountain-ranges that borders it. These mountains were created in ancient times by the collision of a great asteroid which compressed the Lorelei veins and caused the rock to melt and solidify in its distinctive ripple pattern.Penumbric Badlands - The Penumbric Badlands separate Macaree's Tablelands from the Ozymandian Basin.Utrazi Pans - The Utrazi Pans a dangerous region of the Kalidarian deserts which borders Hive Meradon. The Pans derive their name from a great heat sink located beneath the plain which causes geysers of super-heated gas to break unpredictably through to the surface.Vorsanii Aridity
