An NPC is a Non-player Character. Examples of NPCs are Bankers, Provisioners, Cobblers, ect. Some NPCs give quests, some sell items, & give Crafting orders (BODs) You will find a wide range of NPC characters on Heritage. On most servers NPCs also buy items associated with their function, an example, a weaponsmith NPC would buy weapons from players.. on Heritage NPCs do not purchase items from players. This is a Siege shard like mechanic. Heritage adopted this sytle of game play, because "Siege" Perilous is the only "official' server to maintain a stable economy.
