The Soldier of The Elements (I have no clue what I'm doing)

TL;DR, what it's about is that in a war, the military of a foreign planet attempt to survive via the dark arts. Things go bad and it's up to one soldier and brave friends to complete the ultimate soldier to have at least a slight chance in winning the war.
(Please note that all of this is based on my imagination. The first 10-20 chapters are what I wrote on a Google Doc. Also, yes, in the cover is my IRL name but it's only because I had to use it for a school assignment)
