i really think aion has OVERSEXY wings
almost forgot, you can also find the Codex:Angels of Death
specifically about him no, any book. at least by now,guess as the horus heresy series develop we are bound to have a book solely dedicated to the blood angels =D but in Index Astartes II you have quite a lot about him and his legion's background
Yeah Fulgrim is cool too....Too bad he went evil Well....more like imprisoned :P And I also find it sad that we don't have lots of background on Sanguinius...Can't find any books on him :I
my heart is split between Sanguinius and Fulgrim <3
Don't tell me Sanguinius is your favorite primarch too
