Dimension 20: Fantasy High is the first season of the tabletop role-playing game show produced by and broadcast on Dropout TV. DM’d by Brennan Lee Mulligan, this season asks, “What if John Hughes ran a game of D&D?” In this coming of age story, six freshmen of the Aguefort Adventuring Academy try their best to get through high school, and encounter great dangers and mystery along the way. Fantasy High is the first multi-season long campaign produced by Dimension 20, dedicating one season to each year in high school.
Fantasy High uses the font Collegiate FLF for its title, and Proxima Nova for all other displays. This season uses Dungeons & Dragons fifth edition for its game system. It is also one of the very few seasons of Dimension 20 that is fully available to watch for free on YouTube.
After Fantasy High: Junior Year premiered with a new logo, new and current Fantasy High Season 1 related media was upgraded with the new logo. Two notable examples of this are the Fantasy High Webtoon Comic, and the Fantasy High Season 1 and Season 2 YouTube Uploads.
