Adventurers League

The Adventurers League (also termed the D&D Adventurers League) is Wizards of the Coast's flagship organized play program for the fifth edition of Dungeons & Dragons. Since the Forgotten Realms is the core campaign setting for fifth edition, the Adventurers League is set within that world.

Gameplay
The Adventurers League is a continuation of the D&D Encounters program that was part of the fourth edition experience. Stores that are members of the Wizards Play Network can submit reports on the results of adventures, just like they could during the Encounters program, but are no longer beholden to a weekly schedule.

Factions
The Adventurers League reintroduces factions into the game not seen since the Legacy of the Green Regent RPGA campaign. Players are encouraged to join one of five factions based on their class and alignment which will lead to special sidequests and rewards. The five factions are:


 * The Emerald Enclave
 * The Harpers
 * The Lords' Alliance
 * The Order of the Gauntlet
 * The Zhentarim

History
Since Season 4, 3rd Party publishers Baldman Games were given license to write official canonical modules, much like other publishers, such as Kobold Press, Sasquatch Game Studio and Green Ronin Publishing had, while working on the main campaign modules. This was later changed to make Baldman Games' modules convention specific.

Modules
Designed to tie in with the published campaigns, modules made for the League have an overarching plotline that links to the campaign arc currently being focused on. Nomenclature for the module titles indicate that they will be released in seasons. Presumably, these will coincide with changes in the main campaign.

Modules are also written specifically for conventions, but these are not canonical. There are Author Only Adventures, which are large convention exclusives that are only allowed to be run by the person who wrote it. If an author decides to retire such a module, the author can choose to make it a 'Season 0' module, which will then be made available for wider play.

Season 1 - Tyranny of Dragons
The Tyranny of Dragons storyline modules were primarily set in the city of Phlan, though there was also a module set on the Sword Coast. It is thematically linked to Hoard of the Dragon Queen and The Rise of Tiamat.

Season 2 - Elemental Evil
The Elemental Evil storyline modules were based in Mulmaster. It is thematically linked to Princes of the Apocalypse.

Season 3 - Rage of Demons
The Rage of Demons storyline modules were primarily set in the Moonsea region and on the Sword Coast. It is thematically linked to Out of the Abyss.

Season 4 - Curse of Strahd
Also titled "Misty Fortunes and Absent Hearts", The Curse of Strahd storyline modules were primarily set in the Demiplane of Dread realm of Barovia, which are beyond the scope of this wiki, but also included some modules involving the re-taking of Phlan in the Moonsea region and several Faerûnian characters who had been transplanted to Barovia. It is thematically linked to Curse of Strahd.

Season 5 - Storm King's Thunder
The Storm King's Thunder season visits various settlements and nations, including Parnast and the environs of the Greypeak Mountains, Hartsvale, the Nelanther Isles and several sites surrounding Beregost, including Ulcaster and Durlag's Tower. It is thematically linked to Storm King's Thunder.

Season 6 - Tales From the Yawning Portal
The Tales From the Yawning Portal season provides introductory adventures for all of the modules included in the hardcover, framing them to take place in the Forgotten Realms if they were originally designed to take place on worlds other than Toril. There are also Epics for each module so higher-level characters can enjoy adventuring at these sites without being too powerful. It is thematically linked to Tales from the Yawning Portal.

Season 7 - Tomb of Annihilation
The Tomb of Annihilation season is set in Chult, with the added difficulty that until Acererak is defeated, any characters who die while playing cannot be raised from the dead, and if they had been before the season started, they would lose health every in-game day until they died or Acererak was defeated. It is thematically linked to Tomb of Annihilation.

Season 8 - Waterdeep
This season of adventures is set primarily in and under the city of Waterdeep. It is thematically linked to Waterdeep: Dragon Heist and Waterdeep: Dungeon of the Mad Mage.

Season 9 - Avernus Rising
The Avernus Rising season is primarily set in Baldur's Gate The series originally was titled "Inglorious Redemption"; this was changed to "Avernus Rising" shortly after the release of early series documents. It is thematically linked to Baldur's Gate: Descent into Avernus.

Season 10 - Plague of Ancients
The Plague of Ancients storyline modules are primarily set in the Icewind Dale region. It is thematically linked to Icewind Dale: Rime of the Frostmaiden.

Dreams of the Red Wizards
Another set of adventures that can take place outside the continuity of any other season, but released in a way similar to the majority of the other seasons rather than in the way of Season 0. This season does away with low-level adventures, instead concentrating on modules that are designed exclusively for adventurers of level 5 and higher. They are also written in a way that allows them to link into the Ghosts of Saltmarsh hardcover adventure.
