Changes

During the [[Burning of Prospero]] a genetic mutation within the [[Thousand Sons]] [[Legion]] surfaced. {{Fn|1a}}This mutation had not been seen since prior to the unification reunion of the [[Legion]] with their [[Primarch]], [[Magnus]]. {{Fn|1b}}

Once [[Magnus]] and the [[Thousand Sons]] fled to the [[Planet of the Sorcerers]], Ahriman had found a spell in the [[Book of Magnus]] which he called the [[Rubric]]. He thought this spell could cure the [[Legion]] of this mutation , but he needed the help of [[Hathor Maat]], [[Sobek]] and [[Amon]] to form his Cabal and make the spell work. {{Fn|1c}} When Ahriman asked them to join his Cabal they They originally refused to join and help Ahriman cast the [[Rubric]] however , but once [[Magnus]] was elevated ascended to the rank of become a [[Daemon Prince]] , they then accepted to join his Cabal and helped [[Ahriman]] cast the [[Rubric]]agreed. {{Fn|2a2}}

When the '''Cabal of Ahriman''' was formed and the [[Rubric]] was cast , the Legion was then both simultaneously saved and doomed. Although the mutation had was stopped, the members of the Legion those [[Space Marines]] that had little or no sorcerous [[psychic]] powers had been were reduced to piles of dust inside their [[power armour and had become little more than soulless automatons]]. {{Fn|2a2}} After the Rubric was cast [[Magnus]] went to then exiled Ahriman and his Cabal and they were exiled from the legion. {{Fn|2a2}} {{Fn|33x}}
