This is my 'official' time line for the AU Harry Potter stories I am hoping to write in the future. While I do reserve several time frames for my own stories, if you want to write something, please feel free to drop me a line and ask. I will share what resources I use when writing. Something I do not plan to do is much with Ron, so if someone wants to write about his time in the Dark Angels, please feel free. Hermione, while important to the original Potterverse, is not as important here, but I feel she is given justice, being left in the Chapter Library, to do research and learn all she wants. She did not die, bitter, or alone, as she had her books. And I see nothing wrong with Harry finding her notes, and research years after her death and those same notes, helping solve mysteries or even help fulfill future prophecies.

Obviously this does NOT include every battle Harry and company are in, mostly high points in his life, rank and position advancements, and major events.

* indicates a reserved event/time for my own stories. Mostly one Shots but I have plans for a few to be chapter-ed stories

Named Characters so far: Harry Potter, Dumbledore, McGonagall, Hermione Granger, Ron Weasely, Ginny Weasely, Ollivander , Brother Captain Librarian Argus, Tom Riddle, AKA Voldemort.

Naming conventions: I did NOT use the current names from WH40k Universe, but similar names, I am setting this not in the 41st millennium as stated in the roles/fluff, but a couple of thousand years later, so I can freely make up my own time line and names.

(while retaining the rank of Captain, as every member of the Company is at least a Vet Sgt, if not higher), after taking command as Acting Sgt in the field when the Sgt of the squad is taken out by enemy sniper fire in a battle against Cypher, Harry becomes the first person in decades to enter hand to hand combat with Cypher and almost Captures him, but a teleport beacon activated at the last second, saves him.

165*After 4 years of Battle, Harry's original forces have been reinforced several times, but the Last Chaos God has been destroyed, by his own hand, Harry captured Cypher, a year ago, and Harry wielded the Lion Blade to defeat the Chaos God. Upon his return home to the Rock, Harry is promoted to the Chapter Command Squad, the Lion Blade is placed in the Hall of Heros, but every time Harry goes into Combat, and needs a hand to hand weapon, it appears in his hand, eventually the Chapter Command, 'loans' it to Harry. Harry is surprised to find that its not the only weapon he can summon, another broadsword appears in his off hand at the same time. This one has no history in the Imperim, only the name "Godric Gryffindor" on the blade gives any clue as to its true origins, and no mention of that name has ever been recorded in Chapter history. Also anytime Harry entered battle on earth, a strange Red feathered bird was never far behind him and sung a song that filled the Space Marines with courage and fortitude, and helped them to victory.

177*The Current Chapter Master, is wounded, mortally, in combat, and names Harry as his successor. Much debate ensues, but as the Chapter Master it is his right to name his replacement upon his death, and Harry is installed as such. Harry gains a unusual ally, in the same bird creature that followed him in battle on Earth, now remains with Harry where ever he goes. Harry seems to understand what the bird says, and bird understands him completely, and does as he asks... most of the time... the Bird seems to understand any language and can effectively translate if Harry needs.
Harry remembering the know it all friend from Earth, decides to see if she is still alive, to ask for her help in identifying the bird. To learn she passed away several years ago, and no one seems to remember exactly when or how. In remembrance of her faith and courage, the bird is nicknamed Mione.

219 *Chapter Master Harry Potter is wounded by a Chaos Assassin at a meeting of several Space Marine Chapter Masters, the Traitorous Chapter who unknowingly housed and assisted the Assassin is officially disbanded and its members hunted. One of the traitor Chapters Oldest Dreadnoughts is also hit and the Old one inside killed by a direct hit, parts are found quickly to repair the unit and it is decided to encase Harry in the Dreadnought, as he would not survive any other way, Harry is asked to name his replacement, and names the Current Captain of the Deathwing a Brother Marine who served as one of Harry's Lts when he was Company Commander.

273Harry's Dreadnought is damaged in battle, and the Techmarines decide it time for Harry's first Long sleep to preserve his mind for future conflicts.

378After Sleeping the Long sleep for a little over 100 years, Harry is reactivated and sent to fight along side the Deathwing and has many many successful campaigns. The Most successful ones are the ones where the Commander in charge, sought out and listened to Harry's advice, and suggestions.(While at this point, Harry's Rank is effectively nothing, his wisdom and leadership are still highly respected and often sought out, stories of his battles are common and well recorded in the Halls of the Brave).

569Harry's 2nd Long sleep, lasts 150 years.

801Harry is recalled to the Rock, not for a long sleep, but to advise the Current Command of the Chapter. Even being metal and steel mostly. Harry is still regarded highly among the Dark Angels, as well as other chapters, and even some other Imperial forces. He remains attached to the Chapter Command squad for many many years, some even think that the Chapter master himself is but a puppet, and Harry is once again in Command of the Chapter. Glorious battles and victories return the Chapter to its glory.

1000The Techmarines finally insist that Harry enter his 3rd Long sleep, after almost 500 years active, Harry is ready, and finally accepts.

1204*Harry Wakes up from his long sleep, finds out that parts for his model Dreadnought are getting scarce, and is urged to be transferred to a newer model. But declines.

1525Harry enters what will be his last Long sleep, his time spent fighting mostly Orks who have made serious inroads to Imperial space in recent centuries.

1680*Harry is Awoken from his sleep and the Orks are finally pushed back, but not without dozens of planets having to be exterminated due to Ork spores in the soil and air. Harry regains his post attached to the Chapter Command.

1706 *Harry is damaged, his power core is leaking and is unrepairable, the last one of this model was destroyed during his last sleep and Harry has the choice of being transferred to a new dreadnought, or dying and takes the 2nd option. (see first and last chapters of my Story "Harry Potter, Chapter Master").
