Elias will reassure Marco that monsterkind is not in danger from Haftesal's efforts, and that the strange, heavy fog is an anomaly. Haftesal just wants to learn more about the world outside Ryslig, and work towards better human-monster relations! That's good for everyone, right? It's better to know what they're up against, instead of ignoring the strange wasteland fog and being unprepared if it ever breaches the mountain range separating Ryslig from the rest of the world. Marco isn't doing anything wrong!
