"Bill Coffin is a writer of novels and role-playing games. He is probably best know for his work at Palladium Books at the end of the 1990s on a number of Palladium's lines including Palladium Fantasy, Heroes Unlimited, Systems Failure (his own game) and some work on the Rifts line.
Many people consider Bill to have been one of the best writers in Palladium's history. However, due to a conflict with Kevin Siembieda he left the company in 2002, much to the disappointment of his fans.
In 2007 it was announced that Coffin was working on a new campaign setting – Septimus – for the D6 Space core book for West End Games. However, due to financial concerns the publisher canceled the project. In May 2008, Coffin announced that he would release the game as a PDF under Evil Hat's FATE system. In May 2009, West End Games announced that they had agreed to publish Septimus again and that it would be released in August of 2009."
