Though there is no sun visible above, there are shadows in plenty on this roof. Eldritch fires, proton beams, the radiation of Ereshkigal- oh, there are so many shadows...

And the one Garion has chosen lies just along a crack in the rooftop that Shandor fails to see. The bearded man looks this way and that before thinking to look down. "Zi anna-" he begins, and then makes a horrible, crumpling, choking noise. One hand grabs at his throat as he turns purple with both asphyxiation and rage.
