The largest country in the north is the Holy Kingdom of Harmonia, located in the northeastern portion of the continent. Since its establishment, it has assimilated various neighbouring countries, such as Sanadia, as well as a portion of the Grasslands – the Kanaa clan of the Grasslands became Le Buque under Harmonian rule after the First Fire Bringer War. Notably, the Scarlet Moon Empire originally formed after obtaining political autonomy from Harmonia and taking Harmonia's old capital as its own, renaming it Gregminister, resulting in Harmonia establishing a new capital at the Crystal Valley. Harmonia is also home to the Tower, a location reserved for training and housing members of the Howling Voice Guild.
