In game design circles, Brian is highly regarded for his deep knowledge of the Forgotten Realms campaign setting and its extensive history.

Utilizing his website at the time, he compiled lore from many disparate sources into easily referenced PDFs documents that allowed fans to reference each of his entries.

This work eventually caught the eye of senior Wizards of the Coast developers, was purchased by the company and then published as a print sourcebook: The Grand History of the Realms.

He later led the design of Menzoberranzan: City of Intrigue (2012), covering the sinister underdark metropolis famous for birthing the drow Drizzt Do'Urden.

James continues to contribute to Dragon and Dungeon magazines; focusing primarily on content for the Forgotten Realms and Planescape fantasy settings.
