Lifeclay

Lifeclay is a unique mineral found on the world of Galimma created by the magical entity known as the Earthheart. It is a mana-enriched clay-like material that pervades the world's mantle and gives form to the Earthkin races and related geological creatures. For many races it is a precious resource and tool in magic, and sought out by miners and magicians from abroad. It is most abundant in the depths of Subterra, likened to veins of lifeblood that extend from the Earthheart itself.

Properties
Lifeclay structurally allows for the absorption and retaining of significant quantities of mana. It can undergo many geological processes to form other forms of magical minerals such as shield-glass and songrock.

Lifeclay earns its name due to its link to the many sapient Earthkin races, whose anatomy contains significant amounts of the material.
