Devotees of Hala often speak of the Weave, a hidden web of magical power which flows through the natural world. The magic of the Weave is not arcane or divine, but something wholly different, the mystical pulse of the land and all its living creatures. Hags have learned to tap into the Weave and corrupt it to their whims, tangling it like a cat's cradle on their wicked talons. For those who are pure of heart and wise in the ways of magic, however, the Weave can open up new realms of magical power, brimming with all the fury of nature Herself. These are the hallowed witches, spellcasters who have seen the pattern of the Weave and made it their ally, tool, and weapon. Their art is known as witchcraft, and in its pursuit they gather together in covens to fortify their power.
The hallowed witches (or warlocks, if male) are always drawn from Hala's worshippers, though they need not be members of the priesthood. A hallowed witch's divine spellcasting class is often cleric, but druids and rangers are also accepted into covens.
