Merchant House - a merchant specialises in the sales, supply and transportation of commodities. Some might be specialists, such as a Cloth Merchant, a Wine Merchant or Grain Merchant, although many deal with a range of different commodities. A combination of home and business that deals with the wholesale supply of commodities. The wealthy may well order or buy direct from the merchant – but it isn't for the likes of commoners.
Jetty – A small structure projecting into the water that allows fishing boats and other
vessels up to 30 feet in length to be loaded and unloaded. It can accommodate up to 10000 worth of vessels.
Serai - Normally found on the edge of town, a Serai proves basic accommodation for mule trains and local traders. It has pens and food supplies for pack animals, empty storage rooms for trade and a courtyard for cutting deals. Although the Serai doesn’t really provide accommodation, many a small trader or farmer sleeps in the store room with their trade goods.
Shop – Normally a general purpose store, selling a bit of everything. They almost certainly have any normal item that costs less than 1 gp somewhere in their stock, and can probably lay their hands on any mundane items (including weapons and armour) that cost up to 5gp. If you want anything more expensive than that, they will order it in for you.
Warehouse – Used for the storage of goods and commodities.
Office - A basic office for someone who offers professional services.
Toll Booth - used primarily for collecting tolls to use Bridges, Canals and Highways. (restricted to one per item)
Local Market - Full of stalls selling meat, veg, fish, eggs (whatever is caught or grown locally) as well as other small mundane items and services. Think of a cross between a farmers' market and a basic street market – perhaps with a couple of buskers and a jobbing barber thrown in for good measure..
Caravanserai - Similar to the Serai described above, the Caravanserai is larger and can provide secure accommodation for the animals and wagons of a full trade caravan, as well as local traders.
Pier – A structure projecting into the water that allows any size vessels to be loaded and unloaded. It can accommodate up to 25000 worth of vessels.
Stable - Basically a place for storing horses, mules and other similar beasts. If you live in the town and don’t have room to keep you beasts - this is where they live. They also rent animals out, but there is quite a hefty deposit.
Warehouse (Large) – Used for the storage of goods and commodities.
Mercenary Base - Somewhere for your mercenary troops or for your caravan/ship guards to stay and train
Bank – Exchange money for a credit note, get a strong box to keep your valuables (including your credit notes) in. Much safer than keeping them at home. Sometimes built as an extension to a temple of Abadar.
Sword School - a purely commercial sword school that trains all-comers in basic military skills. Good for training your own mercenary unit or guards.
Luxury Store – Furs, jewellery, courtiers and nobles costumes, silver daggers, Objets d’Arte and other posh stuff. Just about anything fancy you might want - at a price. Clothes, jewellery etc must all be fitted to the individual if you want to be really stylish.
Waterfront – A collection of upmarket shops, hotels and lodgings (often by the water side). You can buy all sorts of things here – including luxury and masterwork items. There may be some upscale accommodation and Inn suites in this area are popular with those who can afford them.
Great Market – partly indoors with permanent stalls and part outside with temporary stalls - you can buy all sorts on mundane and exotic items here.
Magic Shop – specialize in the supply of magical items, and act as an outlet for many churches, mages and smaller suppliers as well as buying items to order. There is always a good eclectic supply of magical items here.
