A witch is an eldritch being that is beyond time and space, without a beginning or end. While almost all-powerful in their own respective realms, their ability to affect the mortal realm is limited. They can only affect certain special locations or areas about to suffer great calamity. Witches are also capable of appearing before people in the days or even hours before their own death. 

Witches are extremely dangerous as they are struck by ennui, boredom and their all-powerful status leaves them little reason to consider the sanctity of human life. Many a person has been spirited away by a witch and never been seen again, twisted into a new form to suit her whims. They cannot be permanently killed or even significantly harmed, but they can be pushed back or defeated in combat. Witchguards are hunters who work to try and limit the influence of these dangerous beings.

There are many mysteries surrounding witches. Why do they all seemingly present female? It seems almost highly incongruous no male or even gender non-conforming witches are known of. How are they "made" ?  It's thought perhaps a human could become a witch in certain circumstances but it'd be impossible to track. It's thought that when a witch is "born", time itself stretches back forward and back to accommodate them always existing. This would account for a great deal of the insanity seen in a typical witch's personality.

Recommendation: Avoid however possible

A unique exorcist trained explicitly in fighting witches. They try to intercept incursions into reality by a witch and banish them before they can cause harm. Despite usually being well-armed, witchguards rely almost exclusively on non-lethal attacks and takedowns. This is both for the sake of anyone who may be under a witch's sway but it has its place in fighting witches as well. An intruding witch's power in an area may only strengthen with intense emotion or escalated conflict. Seemingly injuring her can backfire horribly and quickly.

Contrary to the image of "witch hunting", witchguards more frequently employ tactical sprays of water rather than attempting to burn.

An article of clothing, including shoes or hats, created by Rin the Witch of the Norn. Each is made from soul energy harvested from the dead. Witchcloth is still alive but its a strange existence that humans cannot fully comprehend. One without human thoughts and with very different feelings. All witches wear witchcloth and all are supplied by Rin. Unusually, witchcloth can be taken outside of a witch dimension but unless worn by a witch there is only a matter of time before it "snaps back" to where it belongs.  This amount of time can vary from hours to decades.

Nonetheless, witchcloth fetches a high price on the black market. It is highly sought after for its comfort, its ability to fit any wearer, durability beyond all known materials and its relatively ease in cleaning. It is very much contraband, however.

Wearers of witchcloth sometimes report seeing strange but harmless ghostly projections of Rin emerge from them.

A Sphere is simply a "grouping" of witch dimensions that are neighbors to each other. These witches interact with each other more often than they would other witches, whether it's cordial or with hostility.

The Cardinal Witches comprising of Rin, Luxury, the Mourner and Evelyn make up one such Sphere.
