( Sorry for my long silence: Blame ME3. I get distracted... Most things have 'meal' based on how often they eat. Cattle eat a bit constantly. Many predators in harsh environments eat every day or few days, but gorge. Some snakes are known to eat once a week but eat things bigger than them. They slither around all swollen and fat to find a place to lay in the sun... We haven't fed this guy in years. )
"Would you think it is possible to get a cow in here to keep it happy, Attravere?" the Tytalus asks, his eyes fixed on the dragon and his expression carefully held neutral. Iapetus feels a strange mixture of fear and elation, but he's trying to minimize the former... and the latter, actually. Either could get him killed. This is a dragon, after all. In a (hopefully) steady voice, Iapetus will say boldly, "Apologies for the intrusion," in Latin, giving the dragon a nod. It's been harassed by Magi enough it may speak the language, though it seems to be primal in nature. "We merely investigate the situation at hand, and seek no part of your territory." Even if the words aren't understand, putting them there out loud helps Iapetus get the right attitude and stance for non-aggression.
"It seems too convenient to have the shell broken as we enter. If is likely something either triggered the shell's weakening or the dragon's resurgence against it as we passed the Regio borders." Wasn't there something about Aislynn's familiar being jealous of this dragon, thinking that Aislynn'd swap out? That would imply a positive reaction between her and the dragon, which means it's possible.
