Karl's group went home before midnight as the buildings were getting close to complete. The locals could celebrate and fight about their new homes without their presence.
They returned to the Inn for the evening, then made their way to the new house right after breakfast.
The first thing that Karl noticed when they got close was the dilapidated condition of the building. But a split second later, the recognition that the building was not empty slowed his approach.
That could be problematic.
If a group of homeless demons had made the abandoned building their home, he would ruin his hard-earned good reputation to just throw them on the streets. But if it was a criminal organization using this building as their base, it would be even more problematic.
Perhaps this gift wasn't all that it seemed to be.
