NPCs are controlled by Radiant Al, a complex system in which NPCs move about the world in a non-scripted, lifelike manner and perform daily tasks including, shopping or hunting for food, going to sleep, smithing, or even going on a mission of assassination. An NPC can come in many shapes and sizes and be any playable race.
There are also various Unused NPCs which did not make it into the game.
Most of the NPCs in Skyrim are named characters. These characters are all listed on different pages under their relevant name. Quest-givers, trainers, merchants, as well as most NPCs in cities and towns are named characters.
Some named characters are deemed to be Essential Characters. If these characters are attacked, they will fall to their knees and surrender when they get near zero Health. After a short time, they will rise up with full health, and will reengage the attacker until they are killed or are no longer in their zone. The following is a list pertaining to such NPCs:

Details about charactersEdit
All of the characters in Skyrim have two different types of FormIDs that can be used in conjunction with console commands: a BaseID and a RefID. Most console commands will accept only one of the two types of IDs: the BaseID is generally used in cases where a new copy of an object would be spawned, whereas the RefID is generally used in cases where interaction is requested for an existing object.
