Its short, but good. There's a couple concept art shots in there that I've never seen before, but they might be on a collector's edition or something. The piece titled "Monk" looks decidedly un-monklike, makes me wonder if it was connected to Sorrow's Furnace. The crab fort on the bottom is also an amazing piece of work... Possibly a predecessor to the walking turtles for factions, or maybe something for desert transportation in NF that didn't make it. The piece on Abaddon looks waaaay scarier than anything I saw in NF, even if its mainly just an issue of size/scale. As soon as I scanned through them I instantly thought "Maybe they let some concept art for Ch.4 slip through!"... but I highly doubt it
