A. C. Fellows met in North Queensland and lived there a long time. For the past eight years they have lived a long way from anyone on the New England Tableland in New South Wales. They have two children, a role-playing system, and any number of worlds, the most well-developed one of which is Tsai. While most of their works are not strictly co-written, they grow out of a tangled mass of stories, characters, and backgrounds that they have generated together.
