Spells are recitations of power that are often created, utilized and recorded by a species of supernatural creatures called witches. It is unknown how incantations are designed, or why Latin appears to be the default language for most witches when using verbal magic. Catalysts are sometimes required to activate a spell, such as a talisman, as other kinds of magical phenomena are generated and influenced by a witch's sheer will and nothing else. It is shown that for neophyte witches, extra components are needed to perform the most fundamental types of magic, whilst complex and powerful rituals require special ingredients, even for an experienced witch. Spells produce a variety of effects, from manipulating the environment, commanding the elements and even inducing psychic ability.
