Dimension 20 is an American actual play tabletop role-playing game show created by Brennan Lee Mulligan for independent streaming service Dropout. It is an anthology series, with each season telling its own isolated story, mostly with a recurring cast of players. The main cast features Mulligan as the DM alongside fellow Dropout cast members Emily Axford, Ally Beardsley, Brian Murphy (Murph), Zac Oyama, Siobhan Thompson and Lou Wilson. This cast of players are known as the "Intrepid Heroes", while seasons without this core group in full are called "Side Quests". The latest season is Toylight, which airs from September 16 to October 21, 2026. Series overview

Specials
Time Quangle A series of six live non-canonical Dimension20 events titled "Time Quangle" was held in Ireland and the United Kingdom in April 2024. At the start of each live show, performers (the "Intrepid Heroes") rolled dice to determine the characters and setting, pulling randomly from five past Dimension20 campaigns: Fantasy High, The Unsleeping City, A Crown of Candy, A Starstruck Odyssey, and Neverafter. Dropout recorded each performance and released them in late 2024 as a six-episode non-canonical "Time Quangle" series. +TitleDate filmedVenueCitySettingCharacter(s)AxfordBeardsleyMurphyOyamaThompsonWilson"Quangle in Queal Quife"Apr 17, 2024SEC ArmadilloGlasgow, Scotland"Betrayed by Live Theatre"Apr 18, 2024O2 ApolloManchester, England"A Candied Coup"Apr 20, 2024Eventim ApolloLondon, England"The EnWoodening"Apr 21, 2024"The Wrong Kids"Apr 23, 20243Olympia TheatreDublin, Ireland"A New York Quangle"Apr 24, 2024
