AN: Hoping to get a few reviews/PM's on these points which are still up for debate

XI Primarch's name is Albrecht Taranis when he's revealed to the Imperium proper by his father, last name belonging to both a canon character and another OC who will pop up in the soon to be published snippet though only for that particular snippet

Key points

1. Early Content/Snippets will be character development of the XI Primarch (Albrecht) as well as a couple of info dumps

2. Scattering affected Albrecht's Implants resulting in slower growth compared to the other Primarchs (Normal Human Growth rate compared to rapid growth rate)

3. Warp travel/scattering resulted in the XI Primarch being dumped about 200 years into the past (Warp travel is confusing and screws with time to begin with)

4a. Albrecht lived a relatively normal life for a while

4b. Albrecht at one point in his life gets captured by the Dark Eldar and sent to Commoragh

5. Albrecht stumbles upon the Black Library during his escape from Commorragh and spends time there before returning home.

6. By the time Emperor finds him, he has built up a large amount of weapons and equipment both Dark Age human and Xenos (read: shinies)

7. By the Time the Emperor finds him Albrecht has done something similar to what Rogal Dorn has done (built a small galactic power) but has more or less disappeared from public eye when the Emperor reaches him.

8. Albrecht is well over two centuries old by the time the Emperor meets him and has essentially retired. Going to a sort-of normal human life (and all that implies)

8b. Built the Coalition's Occulati Organization, screened and trained investigators (did to them what happens to the Exorcist Astartes chapter: draw a lesser daemon into the materium and let it possess the trainee and then have them force it out) and agents to hunt down and eliminate chaos cults.

9. Emperor doesn't necessarily go on a wild goose chase looking for him, but basically has to spend time looking at what his son has done/accomplishments before he finds him

10. Several Traitor Primarchs don't go traitor due to XI Primarch's involvement with their personal issues, one fixed point is that one particular Primarch gets a certain cortical implant removed. (Whether more than one stays loyal is up for major debate in my mind at this moment)

11. Appearance-wise, Albrecht's original (and preferred) armor is akin to Artorias the Abysswalker's from Dark Souls. When he stays at Terra for some time the Emperor commissions a new set of Armor from the Terran Artisans (The guys who make Custodes Gear) to be given to Albrecht. This is because the Emperor views Albrecht's original armor as crude, inelegant and intimidating (in a bad way) . The aesthetic for the new armor would be akin to the armor of Imperius from Diablo 3

12. In response to the above, Albrecht gets the help of Ferrus Manus (Who was mentoring him on the finer points of Grand-scale strategy and cultivated a friendship with.) to convert his original armor (Which was a basically a sealed-environment suit with metal plates attached) to a suit of Artificer Armor. Wearing the above suit during ceremonies and when he fights beside the Emperor.

the time of the Heresy Albrecht has conquered Northern Obscurus for the Imperium, this was done because his Homeworld was already on the frontier and it was easier to start from there (all the space North of the Eye of Terror such Calyx/Calixis ,Scarus,Finial and Gothic) and has built was amounts to a smaller scale Ultramar (150 or less compared to Guilliman's 500) .

14. That portion of Obscurus is considered an entity akin to Ultramar: a state within a state, Ruled by Albrecht and his Legion, This was done because Albrecht already knew the systems and Malcador and the Emperor saw no reason to appoint governors from the nobility who at the time assumed Obscurus was a backwater region. This in turn set a precedence that Guilliman used to establish Ultramar.

15. No traditional (read: 40k) Forge-worlds in Obscurus. The "Forge-worlds" that exist are closer to research stations, though the Mechanicum did help build several shipyards. This was also due to the fact that Albrecht made conquered and integrated planets self-sustaining.

16. Albrecht cultivated a strong relationship with the Mechanicum, who established a new sect in Obscurus to help catalogue and analyze all of the STC and DAoT items that Albrecht finds.

17. I really should have pointed this out earlier, but the XI Legion and their Primarch are not going to be Salamanders 2.0, Example: Their interactions with civilians/non-combatants are pretty friendly but if there are civilians between them and their objective, they won't care if the civilians get caught in the crossfire. This isn't to say they'll actively target civilians, but they won't necessarily weep over it if it happens
