The Guy-in-Charge points at an alleyway which seems to be serving as a gatehouse to the under-construction keep. "Ya can go in there. Look for a little feller named Kenswa. Best a' luck to ya gents..."

He motions for his team to go around another way. Deliveries must be in the rear. The Keep is of course still in process. So there are no walls to stop people from entering when and where they feel like it.

From what you can see, there seems to be some kind of stage built on top of the roof of the largest building. The catwalks that ring the outsides of the building seem mostly to lead up to it at any rate. Perhaps that's where court is held. Though if so, it isn't being held there now.

So basically, this keep is really four tenement buildings joined by catwalks strung from roof to roof and window to window. There seems to be the intent of merging the buildings together but for now, they are really just four buildings. Something is on the roof of the argest building but for now, you have no idea what.

Obvious options to proceed are: go find this Kenswa guy, follow the cart and see where the painting is being taken, or wander into the buildings and trust the flow of luck.

"Can you detect evil on the unsettling painting, Vaddis ?, Chandanar asks the Iomedean Paladin as they are being introduced to the caste-to-be of the King of Old Korvosa.
"Well, it sure is the first time I hear that a king has been appointed by the People. Does not really feel as strange as it sounds, don't you agree ? And it looks like the man actually cares for his subjects. At the least he has brought some meassure of rationality into the chaos."
The priest pauses and whispers.
"Never mind that I still cannot... appreciate... his tastes as concerns art."
"Let's go and talk to that Kenswa fellow.", he says loud again, though his gaze follows the retreating wagonload.

Vaddis detects evil

The painting is evil, but in an odd way. The best way to put it is it seems more like an echo than the evil itself. For some reason the evil seems familiar. But from where you aren't sure.

So...looking for Kenswa then? 

I was waiting for our detect evil group to decide, but I vote Kenswa

Tarrov nodded at Chandanar.  "Sounds like a good plan.  Maybe he'll know something we don't."  The bard chuckled.  "He is the king, after all."

Kenswa it is. Tarrov, Pitts is the Swatzel Pitts is King Pig. Kenswa is just the door guy.

Kenswa turn's out to be a Dwarf's Dwarf. In other words he manages the neat trick of being surly just through the use of body language. He glowers at you as you walk up to the front 'gate' of the 'keep', tugging on his beard with one hand while the ohter hand taps the point of a knife again and again into a block of wood.

"Well," he grumbles. "Whadda you pretty boys want?"
