Darkfire

After both his parents and grandfather were killed by bandits, Jack sets out on the path to revenge. To achieve his revenge he'll need power, power that only the Adventurers Guild can offer.
To join the guild Jack will need to pass a test, he'll have to complete the Beginners Trial Dungeon in order to advance and receive his starting class. The beginners dungeon is home to many perils, and there's a saying that only one in one hundred people who enter the dungeon survive its trials. Jack is determined to beat those odds and survive.
Sent to handle a simple assignment, Jack stumbles into a confusing plot involving a corrupt priest and an ambitious young Necromancer. Betrayed and thrown into a war he never wanted to be a part of, Jack is forced onto a side, unfortunately for him it's the side that most civilized people either fear, or hate with a passion.
