In the Imperium of Man there are few beings more powerful or important than a chapter master. These legendary warriors are the leaders at the top of their particular Adeptus Astartes (space marine) chapter. There are fewer still more compelling than Lufgt Huron, chapter master of the Astral Claws and owner of an impossible to pronounce name. The Astral Claws were one of a handful of chapters tasked with watching over the Maelstrom, which was literally a wound in reality leading to the warp. They served honorably for a time and Huron rose through the ranks, becoming chapter master when the previous one chased an Ork warboss into the warp. Based on the planet Badab at the time, Huron quickly made his mark and established himself as the planetary governor and became known as the Tyrant of Badab. He essentially took over the sector and ruled it for himself, establishing Astral Claw bastions and purging the ruling elites from the various worlds in the sector. This eventually culminated in Huron ceasing to provide any tithes of gene seed (the magical clone baby essence that makes space marines be space marines) or of money and resources from the planets he now commanded.

This resulted in the Badab Schism (literally based on the rights of the Imperium versus the rights space marine chapters can have in defending said Imperium) and eventually the Badab War. Before the war, Huron and the Astral Claws still served as loyalists, fighting and leading wars against the forces of Chaos. Even after the Astral Claws destroyed Imperium tithe ships and forces sent to investigate what exactly was going on they still were able to continue mustering forces as the bureaucratic nightmare that is the Imperium took their time debating what to do. Well it was solved when Lufgt Huron issued the “Articles of Just Secession” ratified by himself and the chapter masters of the Lamenters and Mantis Warriors chapters. Quite literally a declaration of independence. The response was obvious and a massive 13 year war was fought involving multiple chapters of space marines on either side. Eventually, after heavy losses, Huron was defeated by the loyalists and even the other chapters who sided with him were mostly considered to be misled and returned to loyal service to the Emperor. The Astral Claws were declared Excommunicate Traitoris while the other chapters siding with Huron had to undertake penitent crusades to earn redemption. Huron for his part went full mask off and became a true chaos lord. He and the surviving former Astral Claws formed the Red Corsairs, a heretical warband of piratical chaos space marines and Lufgt Huron was reborn as Huron Blackheart. He began again building his own empire, this time within the Maelstrom warp rift and the realms of chaos.

The Badab war ended up being one of the most significant conflicts in history at least when not taking into account literal end times level events. 13 different loyalist space marine chapters fought in the conflict against 4 secessionist chapters and their massive pool of auxiliaries and defenses that they honed over literal centuries. It is likely the closest thing to a second Horus Heresy that the Imperium has experienced.

On the tabletop, Huron has the rare privilege of having 2 different models. One each for his loyalist and traitor version. They are very old models.
