Sorcerers and Witches, those who practice magic without a license from the religious establishment, often consulted by the poor and underprivileged since the undesirables can’t simply walk into Oz without the right fancy dress.

Thieves, shunned by all since stealing is a greater sin than murder or human sacrifice (mostly because it’s a lower-class crime), but are clever enough to activate wands, identity herbs and potions and use practical household magic, just from ad-hoc experience and fiddling around.
