This story is a sequel to Rising Star

In Rising Star, we saw the introduction of six heroes in Equestria's distant past. Inkwell, Moonchaser, Sunbeam, Lotus Blossom, Dust Runner, and Contrail became enemies of the state when they fought Discord's guards through the city of Everfree. Their identities were protected by disguise magic, but now they - and their new powers - have to fit their way back into everyday life.

Oh, and did I mention that Moonchaser and Featherdancer are currently in Discord's dungeon "permanently?" Which is why when we last saw him, Inkwell was racing off to save his friend and brother after fully stepping into his new role as Midnight Star.

Who knows, if they can keep their secrets and double-lives intact, they might just be able to pull this off and save Equestria... or at least win the battle for Everfree...
