Witches (males are called Warlocks) gain their magic through a closely guarded custom passed down through the generations. Traditionally, it is a magical art practiced only by women, but men may also access the forbidden knowledge of this oft-maligned and misunderstood profession.
Unlike wizards, who learn their spells from tomes, bards who focus the arcane through song and poetry, or priests who gain their spells through divine inspiration and faith, witchcraft is a much more haphazard endeavor, as their spells are gained from the aspects of extraplanar creatures which they allow to possess their body. These creatures are of various levels of scrupulousness, but all hold an interest in the realm of mortals.
The origin of witchcraft is shrouded in mystery, but is said to come from human women who were offered the blood of gods and outsiders to drink in return for power and wisdom. This “gift” has been passed down through generations (often skipping generations), being powerful in certain families, or in other cases dying out in a lineage for no discernible reason. It is the taint of the blood in combination with the exacting nature of her rituals that allows a witch to invoke the various extraplanar powers, often being possessed by more than one at a time to gain a broad access to more magics.
Witch perform rituals by which the spirits and aspects of otherworldly beings are summoned to possess her. She gains access to spell domains and other spell-like powers and supernatural powers based on the nature of that being. Often they contact these being by means of tokens attuned to the spirits, but these are not always necessary to have.
Witches also have access to ceremonial magics, which are elaborate collaborative spells that are cast with other witches and warlocks to summon spirits and powers for great tasks and mayhem.
Witchcraft is often referred to as ‘the quick path’ by wizards, for they rarely seek any deeper understanding of the nature of magic and learn their hodge-podge of groups of spells with no study, bargaining for them and matching their wills against powers, instead of spending days, if not weeks, in the study of arcane tomes and theorems, songs of legend, or in the study of theology or deep prayer and meditation.
In addition, witches are often disliked by both priest and wizards for using both arcane and divine magics.
Witches tend to supplement their arcane powers with herbal, alchemical and healing skills with which they earn a living and/or serve a community.
