The D&D Adventurers League is an ongoing official organized play campaign for Dungeons & Dragons. It uses the fifth edition of the Dungeons & Dragons rules, and features the Forgotten Realms setting. You can play D&D Adventurers League games at any place that features adventures bearing the D&D Adventurers League logo. You can create a character and bring that character to games anywhere D&D Adventurers League is supported.
Most D&D Adventurers League games are public, in-person play events. Typical venues for these events are game and hobby stores, conventions, and public-accessible game day events.
The D&D Adventurers League releases adventures connected in theme to a Storyline Season. Each season is supported by an D&D Encounters season, a series of D&D Expeditions adventures, plus one or more published modules. In addition, storylines will have a variety of cross-media support.
Each season also has an associated Story Origin, which details the rules options that characters may use. However, characters may be created using any active Story Origin and play through adventures connected to any Storyline Season in any order (as long as level restrictions are met).
The Storyline Seasons (as of October 2016) are:
Note: Even after an end of a season, the adventures associated with that season are still playable as legal AL adventures.
The Lost Mine of Phandelver is the adventure found in the Dungeons & Dragons Starter Set. It takes characters from 1st to 5th level. It is an evergreen adventure for the D&D Adventurers League, legal to play at home or in stores.
