The three Bounty Hunters from the Bronze Guild who accepted old man Lance's bounty quest located the lich and confirmed its identity without hesitation, and took immediate action.
They paid to enter the City Lord's Mansion and became its temporary servants.
The lich resided in the City Lord's Mansion, his identity being the mansion's head butler.
They planned to hunt the head butler lich of the City Lord's Mansion, and the head butler lich, too, sought to hunt them.
From the moment they paid to enter the City Lord's Mansion, they realized this, as the head butler lich enjoyed draining the life force of Extraordinaries. Their disguises had been seen through by the head butler lich long ago.
This was normal, as their disguises weren't perfect – background and accents betrayed that they were not residents of Lionheart City or its surrounding towns.
