NPC
From OpenTibia Fans
A non-playable character, aka an NPC, is a common aspect of many games (online and offline). Such a character is placed in the game in order to interact with players in order to guide, trade and provide information as to the game's quests and main plot. Referencing to Open Tibia, These NPCs can be either interactive or they can be monsters.
Tibia and OTServ are no exception to this common implementation; non-playable characters are the main source of trading and provide vital links to numerous quests.
OTServ's NPCs
Currently OTserv uses an NPC system that consists of both XML configurations and LUA scripts.
