The target with the draconic flame salamander which had killed easily more people than it should ever be allowed to, saw Clark.
Itn was ebay for the Mourne family to know who Clark was. This was a student on their list of who to kill if they had the chance. Especially because he was always near the Mourne family waste of a daughter, Maria.
Beyond that the story of the fire killing Clark's parents had not disappeared. Rather, it had grown over time. This had ebbed away at the Mourne family strengths. Mostly because the more distant merchants from further cities or further away locations in the wilderness had heard them and severed ties.
This sort of thing would never happen and many families or large merchant groups would try to impress them. Especially for the wilderness families that sent their own personal merchants yearly.
