Urchive are a type of sea urchins that live within the Blue Grill and are often used by everyone as talismans to ward off Food Spirits that try to possess them.
Most Urchive's often take on the appearance of normal sea urchins, though the spikes around them show to be sharpened down to allow normal people to carry them without any worry of getting stabbed and poisoned.
Food Spirit Warding: The Urchive is most commonly used as a talisman in Area 6, allowing people to walk in the night without fear of being possessed by the Food Spirits that appear. By releasing a powerful stench from their body, it produces a special repellent, similar to how plants produce Phytoncide to protect themselves from insects.
- A similar concept is how people carry around special talismans in Japan to help them with their day.
