OK, my mistake. I was reading up on a link on Vampire Lord somebody posted, and it mentioned that they can walk in daylight freely, but get a -4 penalty to lots of things. But it's clear that Malack is not a Vampire Lord, because of his pale skin (unless he was albino at peak health).
Too bad that the lighting is plot-powered, but I wouldn't have noticed anything if the word daylight hadn't been in the latest strip anyway. It's a minor detail. It's probably true that the increased detail of the strips will create higher expectations, and my comment is no exception.
