Guardians of the Flame 6-7 Joel Rosenberg

Guardians of the Flame is a long-running series by author Joel Rosenberg and is arguably his best-known work. The series is about a group of college students who participate in a fantasy role-playing game, and are magically transported to the world of the game by their gamemaster.

The first book, The Sleeping Dragon focuses on the former students struggling to survive in the world of the game. The series progresses with the students choosing to live in the 'game world' and forming their own community, which is in part based on opposition to the ubiquitous slave trade.

In the later books, the focus shifts from efforts to destroy the slave trade and on to various characters dealing with the changes in the fantasy world wrought by the former students (now mostly 40-somethings). The final three books shift focus to a new set of protagonists, relegating the 'Other Siders' to supporting cast and cameo appearances.
