The following information was shamelessly lifted from the DMG on the Nentir Vale setting, which in my campaign world is a region of the larger area simply known as “The Northland”.

Fallcrest

A small town built from the ruins of a larger city, Fallcrest is the crossroads of the Nentir Vale.

Fallcrest stands amid the Moon Hills at the falls of the Nentir River. Here travelers and traders using the old King’s Road that runs north and south, the dwarven Trade Road from the east, and the river all meet. The surrounding ridges shelter several small valleys where farmers and woodsfolk live; few are more than six or seven miles from the town. In general the people outside Fallcrest’s walls earn their living by farming or keeping livestock, and the people inside the walls are artisans, laborers, or merchants. People with no other prospects can make a hard living as porters, carrying cargo from the Lower Quays to the Upper Quays (or vice versa).

Fallcrest imports finished goods from the larger cities downriver and ironwork from the dwarf town of Hammerfast, and exports timber, leather, fruit, and grain. It also trades with the nearby town of Winterhaven.

The surrounding hills hold several marble quarries that once produced a good deal of stone, but the area has little demand for ornamental stone these days, and only a few stonecutters still practice their trade.

The town is a shadow of the former city; little trade passes up and down the river these days. The countryside for scores of miles around is dotted with abandoned homesteads and manors from more prosperous times. Nentir Vale is a thinly settled borderland where few folk live.

Population: 1,350; another 900 or so live in the countryside within a few miles of the town. The people of Fallcrest are mostly humans, halflings, and dwarves. No dragonborn or eladrin are permanent residents, but travelers of all races pass through on occasion.

Government: The human noble Faren Markelhay is the Lord Warden (hereditary lord) of the town. He is in charge of the town’s justice, defense, and laws. The Lord Warden appoints a town council to look after routine commerce and public projects.

Defense: The Fallcrest Guard numbers sixty warriors who also serve as constables. Moonstone Keep is their barracks. The Lord Warden can call up 350 militia at need.

Inns: Nentir Inn; Silver Unicorn. The Silver Unicorn is pricier and offers better service; the Nentir Inn sees a more interesting clientele.

Taverns: Blue Moon Alehouse; Lucky Gnome Taphouse; Nentir Inn taproom.

Supplies: Halfmoon Trading House; Sandercot Provisioners, Olaf’s Smithy

Temples: Temple of Erathis; Moonsong Temple (Sehanine); House of the Sun (Pelor).

The Town Walls Fallcrest’s Hightown is guarded on two sides by a wall (the river and the bluffs protect the other two sides). It consists of two parallel barriers of stone block with a few feet of fill between them, and stands about 20 feet tall. Every hundred yards or so, a small tower strengthens the wall. Two pairs of sentries (Fallcrest guards from the castle) walk the wall tops at night, but unless danger is imminent, the towers are left locked and aren’t manned. The gatehouses are permanently garrisoned.
