Although Shaer remained silent, the continuous, eerie laughter from Celene almost made Hill certain that someone among the Followers of the Night was trying to sneak in during this journey to cause trouble.
Actually, their interference wasn't hard to understand, at least for those followers who have long served the Goddess of the Night... Shaer's hostility towards Celene and Mystra could never be changed by the seemingly friendly relations she might have with the Undead Tribe.
So in the minds of these followers who excel at stirring up trouble, at most, when causing chaos, they'll bypass Edna and Leonard, Hill wouldn't doubt it. Shaer's followers would definitely not act on their own; they would pray to their goddess before doing anything.
