So for starters, some of the key questions:
1. During Flight of the Eisenstein, I am confused about Rogal Dorn's order to Siegmund to take the bulk of the Imperial Fists to the Isstvan system. I am not entirely clear on what those orders are, but as far as I can gather, the Imperial Fists including Siegmund were at Terra, and they were supposedly not part of the Drop Site Massacre. So what did they do in the Isstvan system?
2. To what degree was the Adeptus Mechanicum loyal to the Emperor, and what did the loyalists on Mars do in response to the traitors?
3. What was the sequence of battles as the fleet led by Horus entered the Terran system? (Including the space and ground battles on the various planets)
4. I would be curious to know about how the rest of the Loyalist Legions which were thrown across the galaxy managed to make it to Terra. The Ultramarines were mentioned to be believed to have been engaged in a major mother of all battles with the Word Bearers, but some of the battles have been vague, such as the case with the Dark Angels.
Any help will be appreciated.
