The lore informations in Three Houses is incredibly plentiful: You got last names, height,ages, mention of places that you don't visit in the name but are relevant to the lore, a whole chronoly of Fodlan, a religion that isn't just some vague 'Good god, evil god' stuff but has an actual organisation with various myths and saints attached to it….

Serious, when it come to writting and lore, Three Houses might just be one of the best FE game.

Im happy the fandom is acknowledging and utilizing the fact that IS provided height information, which is unprecedented
