Story
You've heard stories of great adventures in years gone by, of the heroes who crusaded across the Kingdom of Ehb, battling the stubborn Krug, the poisonous mucosae, and horrifying zombies. You've longed for adventures yourself, while spending your youth sharpening your skills in the quiet little garrison town of Arhok. Now the Shadowjumper has broken free of his chains, threatening the kingdom once more... It is up to you to stop him.
