The Horus Heresy is, in essence, a history of the Warhammer 40,000 universe. It's also a profound IP excursion novel tie-in engine that started in 2006 and is only just now beginning to end.
Here, I will link the Wikipedia page for the series, where you will discover that there are currently more than fifty of these things. This is why you might have to pack them in at odd hours, or in audio formats - especially if you're as late to the party as Mork is. Humble Bundle had an audiobook package in '17 that got me most of the way there. You can pop in and pop out, you don't necessarily need to read every one, but Gabriel is in the burning pit of his ardor for the setting and I suspect he cannot help himself.
As soon as I'm done writing the comic, I'll join Dirty Dwab on the Twitcher for several more hours of Marvel Snap. I was able to manifest excellence on the last solo stream I did, but I think at around Gold rank the type of deck I specialize in has basically run out of gas - I gotta change it up, or become much more accustomed to losing than I currently am. Dabe only got in a week or so ago, I wonder if he's got some ideas. Anyway, it should start very soon after 10am PST!
