@Courier47 on a whim, I looked on the artist's deviantart page.
3, 4, and 5 are parts 1-3 of a sequence called "wrath of the ink" 6, 7, 8, and 9 are parts 1-4 of a sequence called "wireless ink" 1 and 2 are singular picures not related to either sequence.
So this gallery is essentially 2 sequences and 2 individual one-off-pieces organized around a common theme/artist. Thus, these are in the correct (albeit weird) order.
