These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Rescued from the Scrappy Heap: Abaddon. He suffers from at least two memes that make him a complete loser, one because of his thirteen atempts to launch Black Crusades (and since it was barely explained what they were, most assumed he failed all); and the 'He doesn't have arms' meme. With this book, many start seeing in a better light.
