Earth Magic

Earth Magic, also known as Geomancy, is the manipulation of stones and earthen material. It is a branch of Elemental Magic.
=== Overview ===
Earth magic is quite common, and very useful. Earth magic users are able to manipulate stone to an unprecedented level, sometimes able to mold it like clay. As such, they can be incredibly useful in construction, or digging. On a combative level, Earth magic is an incredibly versatile branch of magic; it can be used for defense, offense, and utility.
Earth is considered to be the strongest of the four elements physically, and is the most difficult to break. This is reflected in the nature of Earth magic users, who tend to be very stubborn. The strongest earth magic users are confident and persistent, they will never back down once committed, and are notoriously difficult to beat. However, they are also often cautious, and slow to act in the first place. Additionally they struggle to adapt to new situations.
Earth is adjacent to Fire and Water. Like Fire, it requires a strong willpower. Like water it is tangible and orderly. Earth is completely opposite to Air.
=== Earth Magic Users ===
Anybody can learn Earth magic if they try hard enough, though it helps if they have a natural predilection for stubbornness, and an affinity with stone. Stone is stubborn, and will not acquiesce to a weaker person. An Earth magic user must understand stone on an intuitive level. They usually spend years studying various different types of rocks and analysing their properties. A skilled Earth Mage will instinctively know what kind of rock is beneath them, how dense it is, and how much it weighs. Those who learn magic through study are called Mages.
Earth Sorcerers are born with the innate ability to manipulate earth, an ability which manifests as they mature. Earth sorcerers are usually considered among the least dangerous kinds of sorcerers, due to earth's primarily defensive nature. However, an out-of-control Earth Sorcerer can still cause a lot of destruction.
A less conventional way to access Earth Magic is to become a Warlock, and make a pact with a powerful elemental, or an ancient Earth Dragon. Such beings are slow to act, so gaining such a pact in the first place is a long-winded endeavor.
=== Limitations ===
Unsurprisingly, the use of Earth Magic is limited by the availability of earth. If there is no stone, clay, sand or even dirt nearby, then an earth magic user is powerless.
