Town

<-- You can tell if a location is a Town by the town icon on your World Map (key "M").

Towns, unlike outposts or mission Locations usually provide the full set of NPC services:
 * Collectors
 * Crafters and Vendors:
 * Armor Crafter
 * Weaponsmith
 * Rune Trader
 * Material Trader
 * Rare Material Trader
 * Rare Scroll Trader
 * Guild Emblemer
 * Guild Registrar
 * Henchmen
 * Merchant
 * Skill trainer
 * Xunlai Agent (Storage)

Some towns have road signs marking sections of the town where NPCs offering similar services gather together.

Note that the term town is often used to encompass both towns and outposts, sometimes even lumping in mission locations.
