Location from Overlord by Kugane Maruyama
A kingdom behind a Great Wall that was invaded by a demon army orchestrated by Demiurge — then 'saved' by Ainz, and is now a puppet state worshipping its conqueror.
The Roble Holy Kingdom's tragedy is that its destruction was engineered as a PR campaign. Demiurge invaded as 'Jaldabaoth,' devastating the kingdom. Then Ainz arrived as 'savior,' defeating his own subordinate's forces in staged battles. The Holy Queen Calca was killed. Remedios was discredited. The kingdom's king was replaced by a Nazarick doppelganger. Neia Baraja, who witnessed Ainz's 'heroism,' now leads a 30,000-member cult worshipping the Sorcerer King. The traditional religion is being supplanted. The Holy Kingdom is a puppet state that doesn't know its strings are made of bone.
A nation divided north and south by a U-shaped bay, protected by a 100,000km Great Wall against demi-human territories. Architecture reflects a kingdom built for defense. After Demiurge's invasion, much of the northern territory is devastated.
