A spherical object with small growths and crystalline inclusions, slightly soft to the touch. It takes its name from its CEZ progenitor—the Gum—as if someone blew it into a bubble.\n\n It affects the carrier's gravitational field, distorting force vectors of objects entering its area of influence from outside. A stalker without a theoretical background might mistake it for a Berry.
