Hachisho

Hachisho is an icy land somewhere far north that is a two week boat ride from Ulia. Originally ruled by an extremely corrupt and cruel monarchy, the land, which was already difficult enough to live in due to its climate, suffered tremendously while the rich elites prospered to great heights. After the death of Lady Mileena, Lucifer Deitus left Ulia never to return, and it is heavily implied that by using his power he simply walked across the ocean with no real destination in mind. He would eventually make landfall at Hachisho, and the suffering of the people while the wealthy lived in grotesque excess triggered immense anger within him as it reminded him of his brothers' reign over Haven. After asking the locals for directions to the ones in charge, Lucifer marched to the capital city and proceeded to exterminate both the monarchy and the nobles, forcing the survivors to flee the country and never come back.
After opening up the coffers and supplies to the rest of the country, the people rejoiced and hailed Lucifer as a hero. In awe of the justice he delivered unto them and his immense, strange powers, they overwhelmingly voiced their support for him to become their new leader. With nowhere else to go to, he begrudgingly accepted and has ruled as King since. After Mileena's resurrection at the hands of Lilith, she has returned to his side and now serves as a Queen once more.
The waters west of Hachisho are part of the Northern Hydra's territory.
