Recruitment, Louis's Big Brother
The Earth Alliance Defense Academy covered more grounds and territory than Alex imagined, it also went down a couple thousand feet Underground where there were secret facilities, teaching halls, specialized libraries, and multiple battle arenas, and finally entrance to another Dimension that's not been fully conquered and is used as a training ground for the students of the academy. Some of the Academy's graduates actually live in that Dimension, gaining grounds everyday against the local races in a bid to take it over. It was all very fascinating and quite a new experience for Alex.
The academy itself was like a well planned out town, Alex had seen pictures of places like London the capital of the Albion Empire, places like New York and Seoul and the academy reminded him so much of those cities.
