(Custom fantasy setting I made) A “guardians are the main army unit in “heaven” there’s to heavens. The true heaven where people might go once they die at “heaven” which exist to see if people truly belong in heaven. This guardian is a male. And guardians are just citizens in “heaven” that enlist in the army. Or dead souls from soldiers who got mindwiped and put into the armor the guardians carry. He enlisted into the guardians. He serves the empress of “heaven”. Respectful. Helpful. Sarcastic.”
