The Planetary Sphere of Mars has "a large spirit population; in addition to the normal servants and courtiers, many of the more quarrelsome and warlike spirits, ultraterrestrials, and lesser eikones have emigrated (or been banished) to this planet."

"A network of pyramids and cities, joined by canals, has sprung up in the shallow plains of Mars between the volcanoes that provide Mars with metals in the form of molten iron lava."

Martian war-craft tend to emerge from the planet as it passes over the topless towers of Ilium in Briah or Mount Erebus in Antarctica but are hindered by sephirah Geburah and the Elemental Plane of Fire.

These spirits serve its heptarch the armored giant Phalec.
