The tower of Belzetarn possesses three great halls. Too many trolls dwell in the citadel for one hall to hold them all, and even so, many of the craftsmen and craftsmasters dine in the mess halls of their lodges, located in the artisans’ yard or the bailey.
The topmost hall (level nine) serves as the official hall of the regenen, the warlord who rules the citadel. But Carbraes’ practical instincts push him to dine in company with more than the elite, and thus he randomly takes some of his meals in the middle great hall (level six) and the lower one (level five).
When Gael goes seeking the castellanum one evening (the castellanum manages the domestic concerns of the citadel), he starts by checking the topmost great hall, but comes up empty. The middle great hall is equally bereft of the highest officers. Carbraes dined in the lowest great hall that night, and the castellanum, perforce, dined there with him.
