This is exactly what it looks like. The place to keep track of all your delicious character information. Of course, it's totally not mandatory and up to you how you wish to set it up.

Whether you want to play out your character's childhood or future or you want to enter a completely different alternate universe, this is the place to do it. However, do keep in mind that it won't affect your post count, nor will it count towards your activity on the site, sorry!
