An enormous geographical feature that also serves as capital of Leptax.  Grand Crystalline is a sharp-peaked mountain which rises from deep beneath the swamps of Leptax.  The core of the mountain is composed of thick lodes of silver and platinum, though smaller branches of this can be found running throughout. 

Grand Crystalline is also permeated by thousands of miles of passages which naturally occur between the thick quartz structures within.  It is within that the mountain occasionally reveals new technologies to the Leptaxians.  Leptaxian history holds that it is Grand Crystalline itself which helped facilitated the earliest Leptaxian civilizations.  Today, the city is home to Leptax University and the Imperial Ministry of Health.  Population:  21,000,000.
