Just in case you didn't have enough distractions at work, Lionhead Studios brings us the 'Village Maker' browser tool. Anyone can check it out and customize a totally original Fable III NPC, and a good chunk of the process involves the classic create-your-own adventure all Fable mini-games utilize. Once a personality has been fleshed out, you can pick your NPCs face, voice, and attire from a series of presets.
After that? Well, if you pre-order Fable III from the four retailers listed on Xbox.com -- Amazon, Newegg, Best Buy, and GameStop -- you'll get a code to use on the Village Maker homepage. This allows you to import the custom NPC into your copy of the game, whether for PC or Xbox 360. A tutorial video released by Lionhead confirms that the imported character will have full NPC functionality, from quest-giving to marriage.
The create-an-NPC page is very Fable-y and plays loud RPG music, so be sure to turn down the volume on your work PC before you click this link.
