Dead: Dungeons & Dragons co-creator.

First Gygax, now Arneson. This is why you should always choose the white mage class. From FOX News:

Dave Arneson, one of the co-creators of the fantasy game Dungeons and Dragons, died after a two-year battle with cancer. He was 61.

Arneson's daughter says he died peacefully Tuesday night in hospice care in St. Paul, Minn.

Arneson and Gary Gygax developed Dungeons & Dragons in 1974 using medieval characters and mythical creatures.

The game known for its oddly shaped dice became a hit, particularly among teenage boys. It eventually was turned into video games, books and movies.
