Editing Alternate Heresy (section)

==Replacements==
Replacements are where the story is generally the same up to a point (usually the scattering), but the key difference is a completely new roster of Primarchs and their legions. 

===The Hektor Heresy, AKA the /tg/ Heresy===
{{Main|The /tg/ Heresy}}

/tg/ Creates an Alternate Universe of 40K Astartes legions and discusses how the heresy would play out between them. Since then it has spiralled into a near-total overhaul of the 40K universe as a whole.  Although there are variations in quality and completion, the project feature original art and write-ups for the new primarchs and their legions, original regiments of the Imperial Army, a new take on the Squat, and other warhammerania.
For those interested in the origins of the project: Archived /tg/ threads can be found at http://archive.moe/tg/thread/34414189/ (Initial Legion creation) and http://suptg.thisisnotatrueending.com/archive/34432982/ (Alternate Heresy thread)

===Imperium Asunder, AKA the /tg/ Heresy II: Electric Boogaloo===
{{Main|Imperium Asunder}}

Yet another alternate Heresy with all-new Primarchs, only one where the Emperor is outright killed and Chaos consumes half the Galaxy, while the Loyalists fracture into a number of warring empires on the Eastern Fringe.

===Warmasters Triumvirate, AKA the /tg/ Heresy III: Reloaded===
{{Main|Warmasters Triumvirate}}

A third alternate Heresy with new Primarchs. After the Emperor is incapacitated relatively early on, he leaves three of his sons in charge of the Great Crusade, the Warmasters Triumvirate. When more power is given to the Council of Terra and regular humans, tensions begin to rise. This one has 21 Space Marine legions, pitted against each other in a three way Brotherwar between the Imperial Loyalists, Chaos Traitors and Confederated Seperatists.

===Brotherhood of the Lost===
The Icarion Insurrection = First AU created by Brotherhood of the Lost, started on Bolter & Chainsword, with the starting question being: "What if the canon legions were replaced by lost legion projects?" A three-way war between the loyalists, insurrectionists, and the smaller suzerainty, lasting for decades. This AU has since been discontinued and the writers split into the following two new AU's; The Five Ruins and The Broken Throne

===The Five Ruins===
The newest project from the Brotherhood of the Lost combining old talent with new blood and legions, the Five Ruins project is set in an ever-escalating conflict caused by the disappearance of the Emperor on His way to Ullanor. 18 new legions and Primarchs who are left to pick up the pieces as the galaxy trembles in anticipation of the horrors to come. A compromise situation is reached, a High Regent appointed, but in the process fundamental differences between certain Primarchs or parts of the Imperium develop that are exploited by the forces of Chaos. The Imperium slowly devolves into a husk of its former self as legions fall to Chaos or lead a breakaway Separatist movement, the Galaxy divided and the fate of Humanity uncertain.

===The Broken Throne===
Founded after a certain difference of opinion in the Brotherhood of the Lost project led to the demise of the Icarion Insurrection and a bunch of the creators walked out and took their Legions with them. Warmaster Yucahu of the Void Eagles has been assassinated, the Emperor has disappeared amidst chaos at the heart of the Palace, and the new Lord Regent Kozja of the Warbringers must to pick up the pieces whilst faced with an increasingly violent opposition from other Primarchs. Meanwhile, Ixiplatlan of the Eagle Warriors pulls strings from behind the scenes to incite civil war and spread the reach of the Primordial Annhilator.

Once everybody's figured out which side of this Machiavellian mess they're actually on, the Loyalists must launch an attempt to retake Terra and disrupt Ixipatian's ritual. In the aftermath of the climactic battle warp storms ravage the galaxy, and the Imperium fragments into hundreds of factions striving for their survival.
