Tlaxtlan, known as the "City of the Moon" was once renowned for its astromancers and prognosticators. They observed the moon and the stars in order to make accurate predictions of future events. However with the Great Catastrophe and the appearance of the second moon in the skies above Tlaxtlan their powers waned, as the moon is comprised of pure Chaos and did not obey the laws of the universe, which governed the original moons orbit. Since the time of the Great Catastrophe the Slann of Tlaxtlan have focused their efforts into moving the Chaos Moon from its orbit, and thus returning their power. However more pressing concerns face the Lizardmen and the Chaos Moon, for now, remains.
