Despite the name, this program is actually a NPC mods generator. Mods generated by this program are modified copies of existing NPC records in the Skyrim game data.
NPC record holds data for a multitude of NPC attributes such as A.I. behaviours, skills, hairstyles, eye color, factions, inventory content, spells, abilities and many more.
The software is developed in such way that you can control and every aspect of the game not only the NPC.
