Keltia

Forge World Keltia
This Forge World is located at the Veiled Region and close to the border of the Segmentum Obscurus, and is known as Keltia. This Forgeworld, established in 873. M36, was originally a forward supply base for Rogue Traders and Explorator Fleets travelling further into the Veiled Region (However now, it is not used as a forward base after a Star Fortress was built nearby). It is known for its heavily steam-based productions, be it weaponry, armor, or vehicles. They specialise in developing and mass producing artillery and heavy weaponry for their allies, namely the Guard Regiments of the Taurus III and the Space Marine Chapter known as the Red Suns.

Planetary Physiology Keltia is a planet with an atmosphere covered in dense smog produced by its manufactorums. So much so, that from orbit, the planet's surface cannot be seen, as the smog has created a blanket of gas that envelopes the planet, spanning from the planet's Stratosphere until its Exosphere. This blanket of smog combined with the multiple forges on the planet are the reson for the High Temperature on the planet. The Tech Adepts of this Forge World utilize its molten core to smelt and heat metals used to manufacture weaponry and equipment. The planet's surface, once a wasteland with multiple mountain ranges and dunes, has been converted to kilometers of seemingly unending pipes, corridors, gantries, and forges, that layer the planet's surface with nothing but endless rows of metal that branch out from each other, originating from the Central Forge. Alongside the conversion of the planet's surface, the mountains of Keltia have been hollowed out as a storage for completed productions, and some are used as bases for Skitarii.

Skitarii Legions
The Skitarii of Keltia are known for their swift yet precise strikes and military operations. Instead of deploying en masse with legions of Skitarii present, the Forge World deploys units based on an algorithm that calculates the maximum efficiency on the use of available resources. This is why their military leaders lead their forces analyze the battlefield within seconds and adapt their forces to ensure efficiency.

Heraldry
The Forge World's Skitarii are heralded by blue robes with Martian Red accents, showing the Forge World's loyalty to the First Forge World. The Silver metals of Skitarii in other Forge Worlds is replaced with a brass color instead, that shines brightly, representing the Forge Worlds' Tech Adepts' brazen characteristic, no matter how logical or precise they may be. Macrolades

1st Macrolade - "Knights of the Omnissiah"
The Knights of the Omnissiah are the Keltian Macrolade tasked with crusading in the name of the Omnissiah. Everyone of their tech adepts fights for logic, ancient technology, and most importantly, the Omnissiah. The Knights of the Omnissiah are known for their skill and prowess in combat, as well as their tactical genius. Most of the 1st Macrolade's Tech Adepts do not wear robes with the Keltian colors, but rather wear brass-colored plate armor, and carry banners with their Forge World's red and blue.

Knights of the Round Council
This organization consists of the most intelligent and skilled Tech Adepts who lead the Skitarii under their control into conquests in search of relics, and for the honor and glory of the Omnissiah.

Lord Brenin Artur

This Tech Adept is the leader of the Knights of the Omnissiah. He is the Archmagos of Keltia, and has served under Keltia ever since its establishment. Lord Artur leads his army from the frontlines, as well as a shining beacon of logic and prowess among his peers, and those under him. Lord Artur wields a mighty ancient sword known as Caliburnum, which can cut through a Kastelan Robot with ease. It is speculated that the technology is xeno in origin, and may in fact, be a version of a Xenophase blade.

Black Knights
Black Knights are specialist squadrons within the Knights of the Omnissiah who are mainly used as a frontline unit or as shock troops. Black Knights are difficult to take out of action with their stubborn nature. They will not retreat or falter, as their zeal keeps them strong. Black Knights will very often fight until their very last limb, and even then, their fiery will shall not falter.

2nd and 3rd Macrolade - "Tuatha-D3" The 2nd and 3rd Macrolades are labeled as the Tuatha-D3, and are known for their fierce warriors, and notable Explorator Fleets. The Tuatha-D3 are heralded in the colors of Keltia, and use standard equipment and weaponry. Despite their basic equipment, they are still a force to be reconed with as skilled and tactically inclined warriors.

4th Macrolade - "Victorians" The 4th Macrolade is known as the Victorians, named after a monarch who reigned in the Industrial Revolution of Ancient Terra. The 4th Macrolade uses clockwork and steam-based weaponry, covering the battlefield in smoke wherever they are deployed. This Macrolade is known for its development of most of the Forge World's patterned weaponry, and for its many Excavator and Explorator Fleets.

Secret 5th Cohort - "Medicum Plaga"
The Medicum Plaga are a secret cohort of the 4th Macrolade that resides deep under Keltia's surface. Skitarii of this Cohort are brought alongside Explorator fleets of the 4th Macrolade that are expected to encounter Xeno species. The Medicum Plaga gather Xeno technology and "soothe their machine spirits" in order for them to be used as Imperial technology. The process is costly however, as it requires a 500 year old Machine Spirit that has been treated luxuriously to be transfused with the tortured machine spirit of the Xeno tech. Alongside that, the Xeno Machine Spirit must be rehabilitated and soothed in a process that takes at least 150 years to complete. The end result is a fully functional Xeno weaponry in Imperial heraldry. The Medicum Plaga are heralded by smoke, and do not comply with the colors of the rest of the Forge World's Tech Adepts. Instead, they wear black on their outside of their coats, and bone on the inside. Their brass limbs are replaced with silver instead. The blue glow of their eyes are replaced with a ghastly, lime green. On the respirator is a curved silver beak that strikes fear into the enemy.
