I put up a description in the IC of the warehouse district, the guild district, the plaza of gold, Citadel Teglund, and some of the inside of the keep's grounds. I copied and pasted much of the information from an existing file, so apologies if the textual description is not directly linked to any of the party. Still, as impersonal as it may read, hopefully the description of some of the city and the keep will help you afix an image in your heads about where it is that Wyleck takes you. I tried to order the information sequentially to match the route you're likely to take through the city, first going through the Warehouse District, then up Overtegyrn Byway past the Guild District and into the Plaza of Gold.
A note on the keep. Citadel Teglund lies behind a 50-foot-high curtain wall. The keep's main gate faces east and has been locked with a series of heavy chain for decades. No one goes in or out, ever. Wyleck, being a naturally curious sort, found a crack in the old curtain wall in the Guild District and entered via said crack.
I realize that some of the description is probably more than your characters are likely to know. I shall therefore leave it to each of you to decide, within the bounds of your own common sense, what your character does and does not know of the posted information.
If anyone has a question or questions, please feel free to ask.
