Roy's skin tone was lightened a few shades after the art upgrade. Word of the Giant says it's so he'll appear better when the books are printed. Same thing with Zz'dtri.
For a few hundred pages, Elan has been cosplaying as Locke from Final Fantasy VI minus the wig and bandanna. To be exact, he dressed up as Locke (and Thog donned a Moogle suit) to sneak aboard the Falcon, then gave himself away, got thrown out of the airship, and never changed back. The new costume's a large improvement, though.
Schedule Slip: The author has a chronic illness, which shall remain un-speculated at all costs. As a result, sometimes the comic updates once a month, and sometimes there are five new strips in a week.
