I suppose it's too late to remark that certain cards have colored backgrounds, instead of plain ones like most of the others. I suppose we'll just treat those as special editions or cards that just needed to be accentuated.
Sorry if you find the discrepancy bothersome. It just seemed easier to leave the background on certain images, and I thought it looked pretty cool.
There are 4 cards with a full background, and some with just a few small background elements. And yes, Guntram's card comes from one of the chapter header sketches in the novel, so I left some of his Frost Ravens behind him as uncolored sketches. I rather like the effect.
A few cards featured characters that I don't remember seeing on the wiki or any of your previous works. Are those backer submissions, or just characters we haven't met yet?
They're just characters you haven't met yet. There are 11
cards featuring characters who do not appear in the book, comic, or short stories as they currently stand - and 2 more cards of characters who are only mentioned in the novel, but don't actually appear. But all of these characters will pop up later, and you may have already met a few in forum role-playing games, etc.
And since a couple of the short stories for the eBook are not yet written, they may pop in those. We'll see...
As for the highest-level backers, they aren't on any cards, but all of you guys will appear in at least 2 frames of the final comic!
