=====[[Thousand Sons]]=====
*Recap of the Thousand Sons' history, the Burning of Prospero, the Rubric of Ahriman, and the Siege of Fenris. 
*Tizca is confirmed to still exist on the Planet of the Sorcerers, though it is now mutated into a twisted mockery of its former self.
*The Thousand Sons still have their cults, albeit with a very different focus beyond simply specializing in a given psychic discipline. These include the lore-hunters of the Cult of Knowledge and the reality warpers of the Cult of Mutation. A few different Thousand Sons warbands are also introduced, complete with their own color schemes.
**The further description on how each Cult is organized strongly suggests that the Thousand Sons have significantly increased their numbers since the Horus Heresy; with some extrapolation, their numbers can be estimated at approximately 65,000 Astartes (Rubricae and Living) on top of any cultists and Tzaangors that might be serving them.
*Some kind of major ritual summoning is taking place near the Cadian Gate, overseen by the Cult of Prophecy.
*The dust within a Rubric Marine still contains the Marine's remaining essence. If a Sorcerer can recover this dust and put it into a new suit of armor, the Rubric Marine will effectively be resurrected. In at least one battle, this was used to devastating effect against the Sisters of Silence by dumping a massive cloud of Rubric-dust onto one of their fortresses, which was then followed by dropping a bunch of empty suits of armor down like meteors. [[awesome|The dust reanimated the suits into new Rubrics, and the Sisters were killed]]. 
*After his encounter with Yvraine revealing the Rubric could be undone, Ahriman has determined that the knowledge he needs to learn how to do so is hidden in Commorragh.
*[[Mutalith Vortex Beast]]s are created when dozens of [[Chaos Spawn|unnameable beasts]] end up getting fused together into a single abomination, although some very unlucky Champions of Tzeentch have ended up turning into one of them right as it appeared they were about to become Daemon Princes.
*[[Chaos Dreadnought|Helbrute]]s of the Thousand Sons are not actually created from the Sons themselves due to the unsuitability of the Rubrics to power them. Instead, they lure in members of other Legions/warbands with promises of power and bind their souls to the machines. At that point [[Grimdark|the unsuspecting pilot is flayed and scorched with warpfire while he's still conscious and able to feel it]] before being installed into the sarcophagus.
*Magnus has set a plan an in motion to hyper-accelerate humanity's development into a psychic race, gathering psykers from all over the Imperium to Sortiarius by promising them safety from Imperial persecution. Though his initial ritual is disrupted by the Grey Knights and Dark Angels, the plan itself has not yet been thwarted.
