Fire Emblem: Three Houses is rich with hidden lore and subtle easter eggs. Pay attention to optional dialogue, especially during monastery exploration, as it often reveals deeper insights into characters' pasts, Fódlan's history, and the true nature of the Church. Look for unique interactions between specific characters in different locations. Some characters have special dialogue if they are present during certain story events. Keep an eye out for references to past Fire Emblem titles or other Nintendo games, often found in item descriptions or character quotes.
