Arandor wasn't left alone this night either. The same two buff guys didn't let him sleep alone.
Delirius felt someone's presence all night, someone's eyes constantly watching her.
Thorium spent the night locked up because someone wedged a mop against the door.
There was a slightly dented floor in front of Vistrita's door, resembling some kind of door that reacts to movement.
A suspicious character visited the morgue, rummaged around Reinhard's corpse, and disappeared as silently as he appeared.
At night, as quiet as a mouse, two people tried to break into one of the underground residents' rooms. It seems they were on a mission. Reaching Hermit's room, Vishmaster went in first, and immediately paid for it with his life, only managing to stab the attacker in the throat. The accomplice of the dismembered man didn't linger and disappeared, because he couldn't help Vishmaster's remains anymore. Hermit was unable to pursue the second stranger, and, bleeding, could not resist fate for long and left this world.
