Tellius but in the future. Give me the laguz waifus and husbandos, especially the ravens.
Slavic setting would be cool. This artist made the Three Houses characters with slavic outifts and it looks great. A spookier tone fits the concept. Give me haunted forests, gypsies and creepy fairytales.
Italian renassaince with guns being rare, maybe enemy especific weapons. Gentleman Bastards and gasslamp atmosphere.
Spanish Crusaders, inspired in the reconquista time period and events.
