The story follows a misfit group of fugitives and outcasts who stumble together when a powerful and dangerous arcane relic called The Beacon gets taken by hostile forces, creating a huge risk of basically tear reality apart if they don’t do something fast.
Even though none of them really meant to be heroes or even trust each other that much, they end up joining forces because the threat is too big to ignore and each of them has their own reasons for wanting to stop the disaster. As they travel across strange lands facing enemies, secrets, and weird magical problems, the group slowly starts understanding that The Beacon is way more important than they first thought, holding mysteries connected to the fate of the whole world.
Their mission keeps getting harder as they discover more dangers and hidden agendas, but they push forward anyway because failure would mean everything collapsing around them. The show takes its inspiration from the second tabletop role-playing campaign created by Critical Role, bringing the characters, adventures, and dramatic moments into a darker, high-stakes animated story that shows how unlikely heroes can rise under the right circumstances.
The Mighty Nein Season 1 Episode 7 will be available for streaming along with the other episodes exclusively on Amazon Prime Video.
