Fire Emblem Three Houses - Paralogue: Weathervanes of Fodlan

Annette wants to go to House Dominic to retrieve the Hero's Relic, the Crusher, from her Uncle. Gilbert warns her that if she visits House Dominic, she would become their enemy. House Dominic is currently bending knee to the Empire thanks to Cornelia pressuring them. Despite this, she is determined to go and leaves the Monastery in haste. Gilbert suggests going there too, thinking it would be possible to capture the Dominic region and even came up with a plan; he and Annette will try to negotiate his brother into handing over the relic and the professor and the Kingdom Army will wait outside the region, and if things go wrong, the army will come to their aid.
