The Aberrant Arena is a one-shot adventure with sliding-scale encounters to allow for players of any level, as well as a compendium of martially-focused subclasses and tag-team talents focused on expanding character options not just for this adventure but for your entire campaign. The adventure was written for Tales of the Valiant, and character options are presented for both ToV and 5e.
While the Aberrant Arena adventure can be run stand-alone, it is intended as an interlude in a longer campaign. The adventure takes place in a dream-scape controlled by a mad aberration known as the “Arena Master” who can entrap a party as they slumber. This adventure can take place in any campaign as part of a long rest, after the party is knocked unconscious in a brawl, or falling into a drunken sleep after a night of carousing. The purpose of this style of interlude adventure is to allow a brief break from a campaign's normal flow, whether that is to grant the Game Master time to plan their next story beat, let the players have a reprieve from a stressful story-line, or to fill time while members of the party are unable to play.
