Its not a party per se that Kalath sees. It is in fact a casino, and now that the door is opened he can hear the clatter of dice and the spinning of wheels.
"A casino... we should be able to blend in and slip through."
Kalath looks at the people in the casino and looks around the room. Are the people in the casino diverse enough that he and the Bard could fit in, and is there anything around the room that could make that fit a bit more smooth?
The people in the casino are pretty diverse. There are a couple toughs milling about, looking partially official, but they do not seem to currently be hassling anyone. Kalath can see nothing common to each of the guests.
The room is good size, packed with many people. Blending in should not be hard.
There are many different games going on all over the room and movement through the crowd is slow. No money is in site. All the gambling seems to be done using wooden chips. There are three other doors out of the room, besides of course the one that Kalath just exited. There is one door for each wall. There is a booth next to the door across the room from which an elderly man is handing people wooden chips or taking them back. He is flanked by two very big men. The other two doors do not seem watched or guarded.
Kalath slowly moves with the crowd for a bit, keeping an eye on the flow of people through the doors, especially the door with the booth next to it. He tries to determine how much traffic is going through each door, and which door seems to have the most people coming in from it and/or going into it and not coming back.
The door next to the booth is the most used, but as he watches, Kalath notices that everyone coming in or out is forced to either recieve some chips, or turn theirs in.
The other two doors have only one or two well dressed individuals enter through them as Kalath watches.
Kalath checks one more thing out, just to be sure. Is money changing hands in exchange for the chips, and, if so, can Kalath deduce how much each chip costs?
Also, Kalath tries to see if anyone is leaving bankrupt -- no chips to turn back in.
