Mars in The Fiction of Leigh Brackett - The Moons of Mars

The Moons of Mars

Mars has two tiny natural moons, Denderon and Vashna, which orbit very close to the planet. Terrans generally call them by the Latin names Phobos and Deimos. Phobos, the larger, closer, and faster-moving of the two moons shows evidence of the presence of an unknown race in the distant past that has left monuments that are still little-known. In Low-canal culture, Phobos is sometimes known as the "Mad Moon" and plays an important part in certain rituals (Purple Priestess of the Mad Moon).
