Katze Plains

Katze Plains (カッツェ平野) is a 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 prior to 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 in to deal with and managed to weaken it enough for it to be captured. The undead was transported to the capital of the Empire, imprisoning deep within the vaults of Fluder's magic academy for further research and studying to do.

The Magic Caster of Destroy Arc
It was here yet again that the Re-Estize Kingdom and the Baharuth Empire engaged in one of their yearly annual wars from before. However, this time around is that the forces of Nazarick under the direct command of Ainz Ooal Gown, were participating as fellow allies of the Empire. As a result, the outcome of their battle together against the Kingdom was considered to be a decisive victory for the alliance. The aftermath of such casualties are the complete decimation of the Kingdom's Army including the loss of their strongest warrior, Gazef Stronoff.

Known Inhabitants
The Katze Plains is a haunted place better known as a spawning ground for many old and new forms of undead monsters such as the recent Death Knight encounter by soldiers from the Baharuth Empire five years ago. In other words, these types of monsters that are known to have spawn or at least inhabit this area so far would include:
 * Elder Lich
 * Death Knight
 * Skeleton Warrior
 * Skeletal Dragon
 * Zombie
 * Zombie Slave

Trivia
