The NPC account was created to be used by everyone, when necessary.
What it is, is when you need one or more non-player characters in your RP. Whether you're needing a bartender, an arms dealer, a merchant, a thief, prostitute, town guard, minor villain, even one of your character's family members or friends to show up. These characters are not ones that are played by anyone else, but can add depth and a level of realism to an RP thread. In a sense, they can be thought of supporting roles, if that helps clarify anything. To keep this account from being abused, its password will be changed every now and again. If anyone needs the password, send a PM to me (Azelie) and I will give it to you.
