Duncan left the city without any delay.
He didn't think it was wise to remain in the city longer than he needed to be present. After all, the City Protecting Formation has not been activated yet. The City Lord's office was most probably using his attack to grab more power from the clans.
This struggle between the clans and the City Lord's office gave him enough leeway to escape without being hunted down. The City Protecting Formation can only be deployed by the City Lord. And it is only deployed when facing strong enemies.
Duncan right now had the confidence to go toe to toe with the City Lord. His recent improvements let him know that he had severely underestimated the increase in his strength after the bloodline was awakened.
