Katze Plains

Katze Plains (カッツェ平野) is large plain that is considered a barren land for numerous undeads to spawn.

Background
Surrounded by a permanent foggy atmosphere, the Katze Plains, is where the armies of both Re-Estize Kingdom and Baharuth Empire choose to fight their annual battles. A notable feature of this place is that due to high amount of casualties sustained by both sides every year in their annual war, the place has become a hot spot for many undead creatures to spawn from zombies to skeleton warriors and even Skeletal Dragons. There is also an infamous Elder Lich who haunts the plains on a Ghost Ship that sails the mists that forms frequently in that area.

The Invaders of the Large Tomb Arc
About five years before the current events, scouts from the Baharuth Empire patrolling the area discovered a new form of undead that has never been encountered in this place before and many soldiers were sent to deal with it but most ended up being killed by it. Fluder Paradyne and his disciples were sent to deal with and manged to weaken it enough for it to be captured. The undead was transported to the capital of the Empire, imprisoned deep within the vaults of Fluder's magic academy for study.

The Magic Caster of Destroy Arc
It was here again that the Re-Estize Kingdom and The Baharuth Empire engaged in their annual war but this time the forces of Nazarick under the command of Ainz Ooal Gown, were participating as allies of the Baharuth Empire. The Outcome of the battle was a decisive victory for the alliance and the complete decimation of the Re-Estize Kingdom's Army including the loss of the kingdom's strongest warrior, Gazef Stronoff.
