Sexual Magic

Sexual Magic, also referred to as lust magic, sinful magic, mortal magic, or more commonly "Witchcraft" is in many ways a subschool of the Arcane that appeals to a wide variety of people. Despite its name, Witchcraft is not solely based on sex, but on raw emotion.

Sexual magic turns the power of the soul from these raw emotions (typically fueled by sexual desire which is considered a more "powerful" form of expression) into physical energy to be drawn upon.

History
Believed to have originated with the Dark Elves long ago, Witchcraft has been around for a long time, and was popularized by Humans who took a liking to it. Due to its nature and formation, the Church has had a very hard time putting a stop to it, and in many cases has simply given up due to its popularity among Myn's practitioners.

Most races with the exception of Humans and Elves consider Witchcraft the "poor man's magic" as it requires only mild discipline and developement to implement effectively, and as such are aggravated by it. Still, "witches" find a living in even the most uptight communities due to the remedies and cures they are capable of producing.

Light Witchcraft Vs. Dark Witchcraft
The difference between Light and Dark when it comes to witchcraft can be blurred at times, but it is there nonetheless. "Light" witchcraft tends to focus more on the application of witchcraft to help others. It involves cures, alchemy, and all sorts of light hearted applications of magic.

Dark witchcraft on the other hand tends to focus on manipulating others to acquire what you want personally. It's not very friendly.

Dark witches and Light witches are more than capable of being friends, but their different approaches to magic tend to clash as their approaches are almost idealogical. The light witch is the youthful girl who tries to help others with their problems and ailments (even if for payment) whereas the dark witch is the seductress of a brothel who uses her powers to make the customer pay more money unwittingly.

Demon Summoning
Whether a witch considers herself "light" or "dark," her passionate powers leave him or her far more vulnerable to summoning demons. Many older witches claim to have heard or seen Ravage in their dreams, and a number of them eventually at some point in their career lose it and end up unintentionally summoning a demon (or in rare cases, Devils even). To this end, many consider being a skilled witch as both a blessing and a curse.
