Witches are magic users who borrow the power of spirits and demons. In the past witches were persecuted and hunted by humans, but as of white desire black wishes there seems to be much less prejudice.
all witches have a demonic mark carved into their body known as a witch's brand which appears both on witches and on men born from witches even if they aren't pure blooded.
Withces gain powers from their brand. The power gained by witches range from gaining wealths of knowledge to the ability to manipulate the elements. In some rare cases Witches can summon demons directly from hell to do their biding. While never explicitly stated, all female witches who have appeared in Pandra have had very large breasts and an extremely strong sex drive that often lets them get taken advantage of.
