A liquid, Tallium 40-like Nastium Family quasi-metal. Despite the name, Liquitallium is not in the same period as the Tallium Family, though it exhibits phyiscal properties that resemble those of the Tallium 40(x) series. In nature, it exists in the form of a blue-green liquid, which resists freezing and boiling even in great extremes. It has a high surface tension, like Tallium 40, and it is possible to walk on cold Liquitallium without sinking. Some planets in the Megachidnus system have entire oceans of Liquitallium, which support custom made bacteria and other simple life forms (see Lifeforms).
