Synopsis

Edwin is a tall, strong, handsome young man from a remote but otherwise unspecified village in the faraway countryside, who is not at all secretly an undead mage in disguise. The completely normal Edwin wishes to join the Adventurer’s Guild, an association of government-funded mercenaries that protect the citizens from dangerous monsters that lurk in the wilds.
Edwin’s journey will be a perilous one as he learns to fight, makes new friends, and slowly begins to realize that even the best-laid plans don’t survive contact with the enemy – which, often enough, is none other than he himself.
DISCLAIMER: This is not one of those regular OP MC hidden master stories. Edwin won't suddenly start slinging spells and murdering everyone like he's in a bad anime. While magic plays a major role in the world and the story, the actual fighting contains very little magic, at least in the beginning.
If you're interested in a realism-focused world where people don't just shrug off hits, with a unique, hard magic system, where the main character doesn't have the power to change the course of history but gets impacted by politics and intrigue just like everyone else, maybe have a look.
