A player and NPCs having a sit down
The townsfolk play the purpose of telling you random and sometimes useful information (or just saying your name is nice) and keeping the world a little more alive.
The different shopkeepers will sell you items depending on their profession e.g. a Weapon smith will sell you weapons while the armor smith will sell you armor etc.
Adventurers will wander around not to far away from a campsite alone or in groups from two to four and attack any hostile or neutral mobs encountered.
Some adventurers will also attack or defend the player. Dungeon defenders and bosses are also a type of NPCs.
Some NPCs will give the player a new quest without resetting the time and current quests they have.
