Critical Role is the Dungeons & Dragons livestream sensation, which now has two of its fantasy role-playing campaigns adapted into animated shows for Prime Video. The Legend of Vox Machina (Season 4 is on the way) is based on Critical Role’s first tabletop adventure, whereas The Mighty Nein adapts Campaign 2. It is set in the same world as Vox Machina (Exandria), but takes place around 20 years later, with its main cast playing different characters.

Here’s the official blurb:

The Mighty Nein follows a group of fugitives and outcasts, bound by secrets and scars. But when a powerful arcane relic known as The Beacon falls into dangerous hands, they must learn to work together to save the realm and stop reality itself from unraveling.

Expect an hour-long new animated series starring Critical Role founders and cast members Laura Bailey (The Last of Us: Part II), Taliesin Jaffe (World of Warcraft), Ashley Johnson (The Last of Us), Liam O’Brien (Marvel’s Avengers), Matthew Mercer (Baldur’s Gate 3), Marisha Ray (Fallout 76), Sam Riegel (Teenage Mutant Ninja Turtles), and Travis Willingham (Marvel’s Avengers). The Mighty Nein is described as being “intentionally darker, grittier, and edgier” than Vox Machina. A clip shown during the Comic-Con panel featured the main characters very much not taking an interrogation seriously.

The Mighty Nein main character descriptions:

• BEAU (Marisha Ray): Beau is a Cobalt Soul monk with attitude. Part MMA fighter, part kickass detective, she’s on a secret mission to root out corruption within her own organization and abroad.
• CALEB (Liam O’Brien): Caleb is a disheveled – some might say filthy – wizard with a penchant for fire magic. He’s on the run from his past that continues to haunt him.
• FJORD (Travis Willingham): Fjord is an orphan sailor. After his ship blew up in a deadly scheme, Fjord washed ashore without a scratch and with magic powers. But he’s still trying to figure out if the powers are a gift or a curse.
• JESTER (Laura Bailey): Jester is a loveable chaotic prankster who was born and raised in an upscale brothel. After pranking a powerful politician with no sense of humor, she’s forced to go on the run with her best friend, an invisible god named the Traveler.
• MOLLY (Taliesin Jaffe): Molly is the flamboyant tarot reader for a traveling carnival. His endearing wit is a stark contrast to his mysterious ability to manipulate blood to his will.
• NOTT (Sam Riegel) : Nott the Brave is a foul-mouthed alcoholic goblin girl and a master of stealth and crossbow. She drinks to hide from her painful past, which she hopes her new friend, Caleb, can help her solve.
• YASHA (Ashley Johnson): Yasha is a barbarian woman from the wastes of Xhorhas in the Kryn Dynasty. Her roving mercenary work has earned her the harrowing moniker: “The Orphan Maker.”
• ESSEK (Matthew Mercer): Essek Thelyss is a Kryn elf and elite spy for the Dynasty. He will stop at nothing to protect the ones he loves.

It’s a busy time for Critical Role, which just this week confirmed it has a video game on the way.
