Sea Route of Silence Gang

A group which uses unusual tactics to attack ships and acquire any treasures they might possess. Before any travellers go through the Sea Route of Silence, they stop on a small port town to stock up on food and water, since once they get into the route, it takes two weeks to leave it. While the travellers are stocking up, they find a way to put a Moulding Mushroom in their rationales. Due to the mushroom's properties, it destroys their rationales, leaving travellers to starve to death. When the boat leaves the route after two weeks, with its passengers dead, they come in and take anything valuable.
