NPC is an abbreviation (initialism) for Non-Player Character.
NPCs are the characters that are created by uCool and are controlled by a computer, not a real person. This generally means town/city residents and nomads (i.e. those NPCs with white names). It may also sometimes be used inclusively of monsters.
This page is intended to focus on the former (non-monsters) and their role in Tynon.
