Not one of Harbinder's Snake's mercenaries was left alive.
Sean has known this result for a long time, at least since he said "They are yours", he knew what the fate of these people would be. With those northern barbarians of Iron Wings around, the Harbinder's Snake mercenaries who had already taken away their weapons and armor were completely unable to stir up any more trouble. Even if they resisted, they would be suppressed quickly.
After that, Sean entered a weak state due to adrenaline stimulation.
But for William, he felt that it was a failure that Sean did not pass out on the spot. At least if he had passed out on the spot, there would have been more things to make a fuss about. As for Sean being in such a weak state, William explained to the townspeople that this was because of the side effects of Sean's use of miracles, and he was likely to shorten his lifespan as a result.
