The DL series is a series of adventures and some supplementary material for the Advanced Dungeons & Dragons role playing game. These modules along with the Dragonlance Chronicles trilogy of novels, which follow one possible adventure series through the modules, were the first published items that established the Dragonlance fictional universe. The original DL series was released from 1984 to 1986, with the final two modules added to it in 1988.[1] In the 1990s these roleplaying adventures from the original series were collected and revised for 2nd Edition AD&D as the three DLC Dragonlance Classics modules. There were also versions of the module series released in 1999, 2000 and 2006.
