The fanfiction might play with the technological elements of the 13 Sentinels Aegis Rim universe. It could introduce new types of sentinels or upgrades to the existing ones. This can add an exciting new dimension to the story. Additionally, the relationships between the characters can be explored in a romantic or platonic way. Some fanfictions may focus on a particular pair of characters, developing their relationship in ways that were only hinted at in the original game.
