The PlayStation Vita version of Fallen Legion, both versions have there own story and events following a different main character.
"Claim the throne in Fallen Legion: Flames of Rebellion! Join Legatus Laendur, a cunning general who hails from a land devoured by the Fenumian Empire, as he fights to overthrow the royal family.
Fallen Legion has an intense battle system where you control up to four characters simultaneously. One second your Exemplars are slashing a manticore and the next you’re commanding your team to block right before a magic spell hits to reflect it back at your foes. In between battles, you make split-second decisions that change how the game unfolds. Will you raid an innocent village for a strength buff? Or stand up to a warmongering governor instead of resurrecting a fallen party member? Each choice you make bestows a different power-up and permanently changes the world."
