Village

A regular village is a great way to easily expand your empire and enlarge your presence in a region.
Requirements-

8 furnitured houses in your factions theme.

1 shop or production location. Think about a carpet store, a bakery, a smithy or structures like a mining site, lumbercamp, Fishing hut etc.

1 furnitured village hall in your factions style. (Orcs could have a courtyard as well)

Benefits-

Several spawners that ensure the village is occupied by faction related troops.

1 extra trader for every 8 houses and 1 shop. So 8 houses and 1 bakery could give you a baker npc. But 16 houses, 1 bakery and one smith provides you with a baker and a smith.

Some of the production buildings may earn you extra recources.

Disadvantage-

Higher risk of losing many traders.
