Imperial Castrum

Imperial Castrum (ロイヤル・駐屯地) is a fortified military camp stationed near the Katze Plains. It is used by the Imperial Army during the Annual Wars with the Re-Estize Kingdom.

Background
Located near the Katze Plains, it serves as a marker for where the land of the livings bends near the unhallowed ground. During the Annual Wars, it served as the Imperial Army’s garrison base.

Originally, this place was intended to be the starting point of invasions targeting E-Rantel. That was to say, this massive castrum had been built with the intention of withstanding an extended siege by the Kingdom’s hundreds of thousands of troops.

The Magic Caster of Destroy Arc
Two months after the Baharuth Empire announced its alliance with the Sorcerer Kingdom to reclaim E-Rantel and the Katze Plains, six legions of the Imperial Army assembles at the Imperial Castrum. Nimble Arc Dale Anoch arrived there as well to forewarn the commanding officer, General Natel Inyem Dale Carvain to prepare a welcome for Ainz Ooal Gown. After giving him an imperial salute as a visiting Sovereign, Ain requested to be allowed to bring his forces to the base to participate in the war. Finding it permissible Natel allowed him. Soon after a force of five hundred Death Knights to emerge from a Gate.

Layout & Features
The Castrum was built with huge logs that were nowhere to be found on the surrounding plains, with sturdy walls that denied passage to all in its vicinity. The shallow ditches that ringed it were carefully excavated and filled with sharpened stakes in order to ward against unintelligent undead.

It was built on top of a hill. This hill was not native to the Katze Plains but built up entirely through magical landscaping. This structure had been built over a period of several years.

The garrison could house all of 60,000 knights of the legions, which spoke volumes about the base’s size. This formidable castrum, as mighty as a fortress, was built on a piece of easily defended terrain.

Trivia

 * The Re-Estize Kingdom had no countermeasure against this fortress. Though the nobles would unite during the Annual Wars they bickered over gains and manpower to launch a punitive action towards the base. Hence it was left alone unless it was an immediate threat to the nobles.
