Dave Arneson, co-creator of Dungeons & Dragons, passed away on April 7th at the age of 61.

While Gygax was eventually given much of the credit for the initial creation of D&D, Arneson’s camapign setting Blackmoor would shape the paradigm of D&D worlds, forming the basis of the D&D campaign settings, which have incalculable influence on video game worlds and fantasy novels.
