After the Chaos God, Laharl managed to hear the last prophecy of Ba'al for that day he knew which of three worlds mentioned to strike first, Kolbaline.
As Ba'al went out of his trance noticing his dark master, and father he bowed and spoke to him "My dark master welcome to the Abyssal Library. As you commanded I've have been scrying all through the Web of Time to find worthy of your glorious embrace of Carnage." as the Elder Daemon finished talking Laharl ordered all the Knightmares and the Void Wraiths called Scriptors to leave them as he desires to talk more about Kolbaline, the three Daemon Queens that originate and ascend from that hiveworld, and another crucial important matter of a certain enemy to all Chaos.
The Chaos God of Carnage turned his head to a small table filled with scattered papers, and tomes written by the Scriptor deciding to use it as a chair as the Dark One stretches his wing and speaks "Tell me more about this hiveworld, Great Seer."
Location deep space overseeing the Hiveworld, Kolbaline
A huge planet light up by the various machines, and gothic building with power when the new age of mankind aroused and many left to space on colonizing ships to expand humanity reach and advancements for science, technology, and more one ship managed to find a perfect planet to start a human colony that eventually advanced passed all the levels of technology and science available at the moment as this planet was named Kolbaline which means the "Pinnacle of Evolution" in high gothic, the high lords descendants of the original colonists that follow the teachings and customs set by their ancestors.
Like many hiveworld across the stars they have at first just dedicated themselves to betterment of technology for Earth or Terra that it's on the most desperate moments as the world is falling to Techno-Barbarians and Warlord viding for power before Kolbaline could send resources, support, and soldiers when a gigantic warpstorm the like that 29th Millennia ever seen opened behind the world swallowing the planet whole sending it through the Warp and time for the poor millions of people of the hiveworld it was the worst experience ever as the swirling chaotic forces of the Immaterium then turned calmer and released them in another part of the Galaxy, far away into a sector unknown to the High Lords.
They tried contacting Terra or any other hiveworld but Kolbaline was completely alone so the hiveworld maintain the teachings of the older generations as the hive city drastically expanded and grow to earn the title of the World with "Greatest Technological Advancement" as the lights shun brightly even in the ocean of stars called space.
Location in the Hive City within Kolbaline
Without any support or interruption from other hiveworlds forcing them to backtrack the progress of their research, development, and advancement of all matter of science and technology the people of Kolbaline flourished and thrived with great skyscrapers that actually served to aid the embetterment of the populace and planet itself draining radiation and poisonous smog that is common in many other hiveworld this allowed clean water to still remain on the planet surface and aided in the fields of medicine lead by a group in Kolbaline planetary government called the "Nightingale Convent".
The Nightingale Convent is a group of doctors, and other skilled scientists, biologist from human to xeno orientated as their researching the advancement for the populace, among these members of the convent was a nurse with unbelievable intellect and skill in medicine named Karim Ireneie Von Grimm felt that all her colleagues are just setting her back as she fixed her hair, pull her long sleeves to hide a shame as she read a holopad that activate a secret file of her experiments and research passing all her foolish, imbeciles that are her "colleagues" and "superiors" going to her private chamber as she activate a system that opens a hidden door in her chamber as stair led her to secret chamber were she perform her awful experiments on any unfortunate soul that she managed to get her hands on as the dark chamber's lighting systems and devices powered up many bloodstain metal tables, with several of them with either a ork or a lowly civilian strapped upon them as macabre machines with blades, drills, and lasers as these bodies of Greenskin or Human were still alive despite their surgical removed limbs, opened cavities of her subjects if they complain and scream to much she removed their vocal cords and closing the surgical openings to their necks so they don't bleed out as living experiment subjects is better than a dead one.
As Karim read the latest data she collected she felt something enter her mind as presence complimented, and encourage her research promising more should she listen to it wanting to discover the secrets of the flesh, the improvement of the medicine and science Karim desired this so she accepted as the presence's whispers became clearer and bestowed her with small bit of what she craved as she had to stable herself as the information enter her mind and once the headache ended and more secrets are now in her mind she walks up to the latest acquired experimental subject grabbing a hacksaw and as the civilian placing a breather mask on the subject forcing him to sleep as she rise her blade and brought it down on the person, this is the first Chaos touched soul amongst the populace of Kolbaline.
The Guard of Kolbaline was greatly support with actual recruits offering themselves to join in the defense of their homo with great war-machines like advance Tanks and even Baneblades armed with a powerful energy weapon design by the Underhives of Kolbaline this weapon is a massive cannon safely hidden within the Baneblades themselves capable of destroying a factorum in one shot of it raw energy, and factorums greatly produce these machines, plus the weapons used for the military forces armed with the most advanced version of Bolters, Melters, and Lapsguns for their hundred thousands with the best armor that has even aided them when a Greenskin Waaggghhh invaded while they were confused with the orkz using more primitive weapons and not using "Dakka" they still fought and the Guard annihilated the Greenskins securing their world.
Speaking of the Underhive that has drilled and build the underground core of the planet as the workers, weapon smiths, and more as a great machine that covers the core itself used as a forge for the weapons, machines, and other tech that used by the people above while the populace above thrive and are happy the forger and workers are forced to work in the most dangerous condition by the will of the High Lords of Kolbaline they were bio-engineered to work for the embetterment of the planet and their "human" masters as the doctors and bio-engineers to survive the grim Underhive, these people are more like slaves and are strapped with special collars connected directly to their spine that holds a powerful explosives that activates should they leave the Underhive these "Abhumans" are the Gobos.
