History
Author Philip J. Reed and artist Christopher Shy formed the new company Ronin Arts in 2003 to showcase their talents. The first version of their website sold both the 101 series of books by Reed as well as illustrated art books such as the edition of Herbert West: Reanimator (2003) featuring artwork by Shy.
In February 2007, however, they ended their relationship with RPGNOW due to creative differences.
As of March 2015, Ronin Arts' website is no longer active, having apparently been let go as of late 2012 or early 2013. Many of its products are still available by way of Lulu, Warehouse 23 and Paizo Publishing.
Not to be confused with Green Ronin Publishing, another popular producer of RPG supplements.
