What is paralogue?

A paralogue is a type of side story or bonus chapter in video games, particularly in role-playing games. It is an optional chapter that is unlocked by meeting certain conditions, such as defeating a certain boss or having specific characters reach a certain level. Paralogues often offer additional backstory on specific characters or plot elements, and may provide unique rewards or challenges. In some games, completing paralogues may be necessary for unlocking true endings or unlocking stronger versions of characters.
