Garver replies to Karasu, "I have not led anyone else to this prisoner. I cannot speak as to if others have escorted guests to this prisoner in question."
Garver proceeds to open the door and leads you down several stoen steps into a dingy, shadowed room with three cells. There are two guards down here, who Garve slips a few coins to and the two guards head up the stairs and close the door behind them, leaving Garver and you in this room.
In the center cell covered in paint a man dressed in torn beggar's rags has his feet shackled to the floor by a 3-foot length of chain and is throwing color onto a dirty canvas. Upon hearing you enter the room outside the cell the man stops painting and looks maniacly through the bars, exclaiming through a toothless grin "For you, my master, always for you!" He then sets the painting he was working on atop a pile of other canvases and sets up another blank canvas, madly attacking it with his brush.
He continues to madly exclaim "For you, my master!" at odd intervals and continues to furiously paint.
Isandra and Jalil both find the man to have fairly earned his reputation as the "crazed painter". Jalil, even after his array of detection spells, detects nothing.
