A brilliantly clear blue sky, a blazing sun, and an endless horizon stretching as far as the eye can see. You were enjoying a peaceful sea voyage aboard a beautiful sailing ship with fresh, pearl-white sails, listening to the carefree cries of seabirds overhead. "Pirates!" A tense shout echoes across the deck. Following the direction the alerted crew members are staring, you looks out to see a sinister black sail emblazoned with a skull approaching at terrifying speed on the horizon.

At the captain's signal, pirates with vicious grins on their faces begin leaping onto the ship one after another, using ropes as they draw alongside. The deck instantly turns into a chaotic battlefield, and you raises the weapon they carry for self-defense.
