I'm here, I'm here, I've just been a little preoccupied... and as of late a bit under the weather as well, but I am constantly stalking around here and keeping myself updated on what happens. For some reason I've been surprisingly successful at finding excuses not to post anything, even though they were things that obviously required my response, such as a question aimed directly at me. But since my presence has become uncertain, I will prove it by being here now.

The floor, walls and ceiling of the first room of the barracks lower floor are all made from wood, whereas the second room (the pantry) has three walls of stone similar to the ones found upstairs, with the fourth wall (the one shared with the first room) being wood.
As to the architecture of Zerul - by which I assume you specifically mean Zerul City - well... Eh, I just tried tried to do some quick research on architecture to find something to reference, but it's too much of a bother for me right now to get past the volumes of results specifically pertaining to religious buildings and castles to find something about more common structures. But generally the Zerulic citizens favor cleanliness in their buildings more than those of the other duchies, making white, beige and cream the predominant color of exterior walls there, usually with gable roofs with shingles typically made of wood, although wealthier structures - particularly those situated in the northeastern central part of the city, where the Magic Academy of Zerul lies and sorcery generally runs rampant - are known to use slate shingles instead. Walls are typically made of stone, and while load bearing walls are usually relatively solid, Zerulics like windows; the bigger and more numerous, the better. They also like arches, and many windows and doorways (with those that can afford it) have arched tops, and if they do not have protruding frames all the way around they can at least be expected to have an exterior windowsill, the most popular color of which is currently red. Walls are almost exclusively made of brick, and the shape of buildings is usually relatively squat, with buildings often being elongated and more rarely squarish, but always rectangular, and usually no more than two floors tall, meaning that each building takes up more horizontal space than the buildings found in the other cities; basements are relatively common, but usually small. The Zerulics are not fond of columns but, once again, like arches and fountains, and as such these can be found in most wealthy estates, which also like to boast of neatly trimmed and utterly domesticated gardens that are obviously artificially arranged (I hate those...). Towers are rare and reserved for important official buildings, the only ones to have more than one being the Castle Zerul and the Academy, and are always circular in shape and with conical roofs at their tops.
This is all mainly pertaining to the middle- and upper-class of the citizens, though... Obviously these kinds of homes are expensive, though slightly cheaper in Zerul than most other places. Less extravagant homes usually still have stone walls, though often in the natural color of the stone, with far fewer windows but still with wooden shingles; wooden walls and thatched roofs are rare and are almost exclusively found at the outskirts of the city. They are also smaller and much more ordinary in most respects... generally something like what we are used to seeing in movies and such as the homes of peasants.
Was that a satisfactory description? Did I miss something?

@sartorous: I should have responded to your posting your CS earlier; I let myself postpone that bit for far too long and with too little justification. I'll add a link in the OP... But does my memory fail me, or has Salas' weapons changed? My memory is not good enough to pick out other possible inconsistencies, but something in the back of my mind tells me that he had a different selection of armaments before...
Also, any thoughts as to how he survived the Battle of Anaxim Forest, or where he is going to go now?
