Elementmancy

Elementmancy is an ancient skill in Tamriel, which slowly grows in power and number of people whop use it over the 200 years between the Oblivion Crisis and the Dragon Crisis. It is used by many skilled and dangerous people, the two most well-known being Elana Indoril and King Asin.

It is a very dangerous power, however, as some very skilled users have been able to create wanton destruction.

Hydromancy
Hydromancy, or water manipulation, is the ability to control water and bend it to your will. The term 'water' loosely applies to ice, snow, and precipitation, as well.

Different Styles
Dunmeri Hydromancy:

Dunmer hydromancy is less rigid than the other types, as each hydromancer seems to flow from one move to the next, never planting their feet solidly. Dunmeri Hydromancers rarely, if ever, use ice and snow, due to their land being a volcanic wasteland.

The Dunmeri prefer to draw water from any nearby sources, and they frequently have to be resourceful, drawing water from the soil, plants, and even the air!

Altmeri Hydromancy

Despite the fact that the Altmeri are considered to be graceful and refined, this does not seem to carry over to their hydromancy, as their skills with the power are widely considered to be the most uncouth and rough. Altmeri Hydromancers frequently take rough steps during their mancing, and prefer to blast their opponents with powerful hose-like shots, instead of waves.

The Altmeri, due to their island homeland, are not as resourceful as the Dunmeri, and draw water from any large body they can. However, as they live in a tropical environment, they rarely use ice or snow, as well.

Nordic/Breton Hydromancy

Nordic and Breton Hydromancy is widely considered to be the same in style, and this much is true. They have a more... offensive style, more alike to the Altmeri Hydromancy than to the Dunmeri version. They frequently use ice and snow, due to their northern climates.

The Nord and Breton users of this skill prefer to hit their opponents with quick, powerful blasts, never staying in one place for two long, nor drawing water from one place for two long.

Subskills
Blood Manipulation

The name says it all. Few people are skilled enough to learn this power, but, when they do, it is very hard to defeat. Able to bend the body and skills of others to their own will, blood manipulators are powerful and dangerous enemies. It is better for any potential opponents of a Hydromancer to make sure that they do not know this skill...

Pyromancy
Pyromancy, or fire manipulation, is commonly confused with destruction magic, which uses fire, also. However, pyromancers do not expend any Magicka, and their fire is much more powerful and deadly than that which comes from any average mage.

Different Styles
Imperial Pyromancy

Imperial Pyromancy is much more rage-driven than any other style, and Imperial practitioners go more on the offensive. They derive fire from their own soul, and many pyromancers grow angry and cruel after a few decades of having this skill.

Imperial Pyromancers prefer to fire off quick blasts from both their hands and feet, and overwhelm their opponents with a sheer number of attacks.

Orcish Pyromancy

Like Imperial Pyromancy, orcish pyromancy is very rage-based, even more so than the Imperials. They derive fire from their own stamina, so many pyromancers grow very tired and lethargic, after a few decades of using this skill.

Orc Pyromancers let forth long blasts of fire from their hands and mouth, trying to bring down their enemies without wasting too much of their own stamina.

Redguard Pyromancy

Redguard Pyromancy is more spiritual, using their own passion to fuel their fire. Redguard Pyromancers use their heart, and thus, the fire is different colors, depending on the pyromancer. However, as they expend their own passion, many Redguard Pyromancers become very bland, with little emotion.

Redguard Pyromancers are very versatile, able to let forth long or short blasts. However, they usually lose themselves in the heat of the battle, and can lose control.

Subskills
Heat Manipulation

Heat Manipulation enables the user to draw heat and energy from another person, before letting them forth in massive, fiery explosions. However, frequent use of this skill drives many people insane, due to the fact that they take a little part of someone else into themselves.
