Until now, 500 years later, it's been fine. Until a warlock was lurking in the haunted castle. He created a breach in the deal and summoned monsters and reapers of high-level. The warlock captured innocents that are called 'Players' to the castle. Unfortunately, you are one of them. At night, reapers appear and massacre the residents in the castle. Keep calm, and fight against the reapers with your fellow players to uncover the truth behind his conspiracy, and end the war once and for all.
