[Chapter History: Unknown to Imperium of Man, a few of the Space Marines of different chapters, lost in time and space, unite as one to face the archenemy of mankind and other Xenos factions. Selected by fellow Space Marines, William Nullinanis from the Black Templars led his fellow battle-brothers and other lost servants of the Emperor in the unknown world only known as New World.

After discovering and using a legendary relic known as STC, William found a new kind of elite warriors and the Astartes chapter. Utilizing the previously lost gene-seed of the grey Knights and genetic constructor of the STC, the Legion of Blacksouls is founded to deliver true death to Emperor's enemy.

The Legion of Blacksouls is composed of 1000 Astartes but capable of recruiting more as their max capacity could reach 10,000 Astartes. As Space Marine, Blacksouls (Short name for the Chapter) receive multiple gene-seeds but source directly from the Emperor himself and later modified to perfection. This gives Blacksouls greater physical build and near unbreakable physiological ability compared to standard Space Marine.

A certain number of Blacksouls can demonstrate an ability known as psychic null. Members who possess this ability go through rigorous training to become chapter Librarians, but unlike standard Space Marine Librarians who can utilize the power of the warp, Blank Librarians cut the links to warp around them, making Psykers useless.

The war gears of the Blacksouls are made of powerful relics recovered from the STC. The Chapter Master of the Legion of Blacksouls possesses legendary Hercules pattern terminator armor, believed indestructible and invincible on the battlefield. Armed with a golden halberd and earthshaking power hammer, the melee combat isn't recommended to anyone who challenges the Chapter Master. As for the range, the Hercules is equipped with a power fist heavy combi-bolter, power gauntlet combi-plasma. The armor is also equipped with an Iron Halo, a teleportation device, and a null amplifier (Similar to Culexus Temple Assassin's Animus Speculum).

Chapter Master's Honour Guards are specially equipped with STC relic weapons and armors that could match even the Adeptus Custodes war gears. Elite of among elite Veteran Space Marines, Honour Guards earn their positions through courageous service to the Chapter and deed equal to legendary status within chapter history.

The standard Blacksouls Space Marines are given additional gene-seeds including organs that allow them to bring out blank ability. As each and every 'Null Marines' possesses a blank organ, they are immune to the negative ability which prevents friendly fire from the Blacksouls Librarians.

The first company is comprised of terminator armor units with access to the Chapter's most powerful weapons and devices. The first company is composed of veterans and most tested Astartes with years of experience to quickly determine the enemy's weakness during battle.

The second to the fifth company is made out of Astartes armed with ancient weaponry that could only be recognized as advanced technology. Each Space Marines has access to at least three different kinds of bolter ammunition at all times besides the standard bolter ammunition. As for their armor, each Astartes possess powerful power armor compared to the first-born Space Marines, which could withstand heavy weapons that could destroy standard power armor.

Because they do not have a homeworld, the Legion of Blacksouls recruits from world to world as they travel the void. Everything can be done in the Fleet, from training to constructing new vehicles. The Fleet only makes a stop to the Imperium world only to recruit and resupply. The fleet ships are composed of 50 ships and big enough to declare crusade on their own. It is up to Chapter Master to claim one Imperium world as his own if he desires, and with his authority, the fleet-based status can be changed once the world is claimed.

Each Space Marines is encouraged to learn many different skills that other chapters would specialize in. Because the Legion of Blacksouls is composed initially of different chapters, the Blacksouls took each of the best traits and added them to their own. The Blood Angel's artistic cultures and close combat, Salamanders smithing and customizing, Ultramarines' battle tactics and all types of strategies, Black Templars' void war (Space battle and fleet command), and Space Wolves' ability to wage unbreakable will and battle ferocity.

Using the war tactic of Ultramarines, the Blacksouls can analyze the battle situations, reorganize and react accordingly. They do not strictly follow the codex but accept specific war advice from page to page. The Blacksouls are masters of melee combat since they utilize the null-ability to neutralize any warp ability and connection to the warp. For this reason, Blacksouls prefers to drop directly at the enemy line to maximize the use of blank ability and sever the enemy into two while frontline companies advance with mid-range weapons and heavy vehicles.
