Editing Imperium Secundus (section)

===Intention===
Guilliman was aware of what his new Imperium represented and did not need to be told by his brothers how heretical it was.

In his own mind Imperium Secundus was '''"Plan B"''' - an outcome less desirable, but something you can live with.

Despite this, Guilliman was fully prepared to fight for what he believed in and even related to his officer [[Remus Ventatus]] (in the same conversation when he iterated that the [[Codex Astartes]] should not be adhered to religiously) that he should even be prepared to fight against those brothers who counted themselves loyal to the Emperor, and later commented that when he was about to declare the Imperium Secundus official he was ready to kill anyone who would stand in his way (what a traitorous scumbag).

Furthermore, the fact that the [[Codex Astartes]] was written well '''before''' the fall of the Emperor shows that it was obvious that Guilliman believed that HE was the only person capable of safeguarding his father's legacy regardless of what [[Leman Russ|his]] [[Rogal Dorn|brothers]] [[Corax|might]] have thought in the aftermath of the Horus Heresy. Guilliman planned it all well in advance and was willing to back it up with force ... Since the aim of the Codex is to neuter the strength of other individual Primarchs.

In retrospect, his insistence on leading the Scouring was likely his way of trying to atone for his failure to return to Terra sooner.

On a final note, keep in mind Guilliman ultimately got maneuvered into creating Imperium Secundus. [[Kairos Fateweaver]] and [[Lorgar]] arranged things with the [[Battle of Calth]]/Ruinstorm/Shadow Crusade precisely to starve Guilliman from information, keep him busy in Ultramar and put him in a position where '''Plan B''' looked like the best possible option, all in a concerted effort to keep him and his Ultramarines away from the battle of Terra.
