Its very controversial, but in the online community the concept of an npc is taken from the acronym. You see, it starts with testing at the core of the letters prior to reading and continues when you inspect every single letter in the acronym. If it does not meet our standards of an acronym then the delivery to the brain of the knowledge of what precisely the acronym is, is simply rejected. But if it is an acronym, you would come to the conclusion that an NPC is a Non Playable Character and all of the thought process you initiated firstly is successful. This thought process for identifying acronyms is closely monitored by the staff team, like all thought processes, to ensure there are no misunderstandings. Ever.
