This is a D20 product by Wizards of the Coast. They have taken Robert Jordan's world and inserted it seamlessly into the system they created for D&D 3rd Ed. It was done with the assistance of Mr. Jordan himself. This is perhaps one of the best adaptations of the D20 system. For all Wheel of Time fans, and D&D players who would like to take on the Forsaken, this is a must. It won't disapoint you.
