Special Abilities
Elemental Meld (Su) A quartz elder has a natural and total control over earth elementals within its tremorsense field of less than Gargantuan size, and can meld with the form of an earth elemental of at least Huge size. The earth elemental loses all attacks and earth glide, but the quartz elder now has its move, burrow speed, and earth mastery. As a melded creature, all attacks are 50% likely to hit the earth elemental, and 50% likely to hit the quartz elder in this configuration.

In a lost era, strange beings of crystal and minerals existed in a mostly sessile state, contemplating the depths of existence and reality. Fully sentient beings composed of crystal and stone, quartz elders have developed powers of mind and magic to survive the machinations of moving things, and to further their own inscrutable plans.

Though appearing as a single translucent crystal of various shades, a quartz elder can be easily mistaken for a chunk of relatively normal stone, which it sometimes does to ‘infiltrate’ flesh-and-blood society. Some subterranean races have attempted to worship quartz elders, and a few of the ‘crystal ancients’ allow this, if only on a temporary basis.

ON PORPHYRA
Many quartz elders house the spirits of elemental elders defeated in the ancient power struggles between singular intelligences on the Elemental Planes, banished to the Material. More recently, some quartz elders are the housed essences of defeated Elemental Lords and their lieutenants, fleeing the NewGod Wars.
